You have a 0.1 mole/sec stream of propane at T = 400 K and P = 7.5 MPa. You isothermally and reversibly compress the pressure to 10 MPa using a intercooler

compressor. Find the amount of heat dumped into the environment and the amount of work needed to compress the propane.

You are working on a feedwater system for a chemical engineering plant. A section of the pipe passes through a stream of width ? = 4 m which flows at constant temperature and velocity (?∞ = 12 °C,?∞ = 1.7 m⁄s). You need to determine the temperature change of the feedwater as it passes through the stream. The feedwater is 20 °C as it enters the section passing through the stream. The pipe diameter is 4 inches and the volume flowrate is 50 GPM.

a. Calculate the Reynolds number of the water flowing inside of the pipe. Is the flow laminar or turbulent? (We can continue with this problem either way)

b. Calculate the heat transfer coefficient in the pipe. The thermal conductivity of water is 0.6 W/m-°C and the Prandtl number is 7.5. Use an appropriate laminar flow correlation, or assuming fully developed turbulent flow, the Dittus-Boelter correlation is appropriate: ?̅̅̅?̅ ? = ℎ̅? ? = 0.023 ∗ ??? ( 4 5 ⁄ ) ?? (0.3)

c. Calculate the temperature change of the water assuming the pipe wall temperature is equal to the stream temperature. The specific heat of water is 4200 J/kg-°C. Use the following transformation for integration: ?(?) = (?(?) − ?∞)

d. Calculate the total heat transfer rate.

1. A food processing plant makes soup in a continuous process with a steady flow of product into and out of a large kettle. The soup is maintained at a certain temperature by heating the kettle with a coil of steam pipes. The large size of the kettle means the entering product remains in the kettle for a long time. Draw a graphic and describe how the plant could use feedback, feedforward, and cascade control to maintain a constant temperature. Which control scheme would provide the tightest control?

A solute A is being absorbed from a binary gas mixture of A and C into a pure solvent B in a packed tower with a cross sectional area of 0.2 m² at a temperature of 300 K and pressure of 1 atm. The inlet gas contains 3 mol% of A and its desired to remove 85% percent of A from the gas stream. The feed gas flowrate is 14 kmol/h and the solvent flowrate is 45 kmol/h. k_y’a_h = 0.04 kmol/m³s and k_x’a_h = 0.06 kmol/m³s. The equilibrium relationship can be assumed y = 1.2x.

What is the packing tower height?

The mixture of A (LK equivalent) and B is to be separated through the distillation column connected with the total condenser and the partial reboiler. When the specified-liquid feed (F; 100 mol/h) containing 50 mol% of A is supplied and is operated through the design conditions below. The composition of A in distillate(D) was 0.96 and the composition of A in bottom(B) was 0.18

(a) Calculate Total equilibrium units (including partial reboiler)
(b) Calculate the location of the raw material supply (a number of positions down from the top plate);
(c) calculate the slope for each control line.

However, the relative velocity (αA-B) of A and B is 2.57, and the answer (a) and (b) is an integer.
Design conditions: The operating reflux ratio is set at 1.83 times the minimum reflux ratio (Rmin).

You just ordered a batch of sodium hydroxide (NaOH) which is used to lower the pH of a solution during a process your team supervises. You need to get a quote for transportation from the closest port to your company's facility, but the trucking company charges by the ton and you don't know how much your load weighs. The international vendor is closed and you can't call to ask due to the time zone difference so you just have to figure it out.

According to the manufacturer, the density of NaOH is 52.3 Ib/ft^3. It shipped in cylindrical drums which are 22.5 inches in diameter and 33.5 inch tall and weigh 27.4 Ibs when empty. The shipping container is 8.0ft wide, 8.5 ft tall, and 20.0ft long. The empty shipping container weighs 5,000 Ibs.

(a) Assuming the drums are filled to capacity, calculate the mass of a single drum of NaOH. [mass = volume x volume]

(b) Calculate the total number of drums which can fit into the shipping container assuming they are packed in even rows and stacked on top if possible. [Hint: You can't have a fraction of a drum, it would leak all over. They get stacked just like boxes]

(c) Calculate the total mass of the shipping container full of drums and be ready to get a quote from the trucking company tomorrow.

(d) How does the total mass of the shipping container change if the diameter and height of the drums decreases by exactly 50%. Assume that the mass of the empty drums scales linearly with volume. In other words, if the volume decreases by 1/3, then the mass will also decrease by 1/3.

Use the psychrometric chart to estimate (1) the absolute humidity, wet bulb temperature, humid volume, dew point, and specific enthalpy of humid air at T =30 oC and 40 % relative humidity, and (2) the amount of water in 150 m3 or air at these conditions. Students must sketch the psychrometric chart and draw the path of determining the parameters of (1).

A steam boiler of volume 2.3 m3 initially contained 1.7 m3 liquid water in equilibrium with
0.6 m3 of vapour at 100 kPa. The boiler is heated keeping the inlet and discharge valves closed.
The relief valve is set to lift when the pressure in the boiler reaches
5500 kPa. Determine the amount of heat supplied to the contents in the boiler before the relief
valve lifts.

he Deacon process uses hydrochloric acid and oxygen from air to produce chlorine gas and

water. Air is fed into the reactor at about 35% excess, and the fractional conversion to chlorine gas

is about 85%. Procurement needs to know how much acid to purchase, and we are thinking about

using 37% w/w HCl (12M), which has an overall density of 1.19kg/L. How many litres of this 37%

w/w HCl should we purchase per week to get 100,000 litres (STP) of Chlorine gas per week

Compare Step Counting method and detailed factorial method (Hand method) in terms of calculation constraints, calculation accuracy, design details availability and cost data availability. Then determine the best method to employ in this case.

A gas mixture consisting of 10% ethylene gas (C2H4) and 90% CO2 by mol is combusted with 50% excess air via the following unbalanced reaction: C2H4 (g) + O2 (g) à CO2 (g) + H2O (g) Air for the reaction is brought in from outdoors and cooled through a chiller to remove any humidity. The combustion product gas is pressurized so that all water vapor is condensed into liquid, which then combines with the water from the air chiller and exits through a separate H2O stream. a) Draw the process flow diagram. b) If the outdoor air has a dry bulb temperature of 30°C and 30% relative humidity (RH), how many mol of water leave the system (in the combined H2O exit stream) per mol of ethylene combusted? c) What is the molar volume (in L/mol) of the water-free combustion gas if it is pressurized to 150 atm at 20°C? CO2: Tc = 31.2°C, Pc = 72.8atm O2: Tc = -118.6°C, Pc = 49.8atm N2: Tc = -147°C, Pc = 33.5atm

For the dissociation reaction: A2(g) ⇌ A2(g)  
is the equilibrium constant K=0.347 at the temperature T=300K, when the status of the standard is adopted (in other words partial pressure 1 bar for gases).

A) Calculate the ΔGr for the reaction at T=300K

^{B) calculate at which total pressure the molar fraction is 0.280 at 300K for the mixture.}
