Saturated water at 20 C flows inside the annular region formed by two concentric circular tubes. The OD=71 in mm, while the ID= 101 mm, The mass flow rate is 0.02 kg/s. , The outer surface is insulated, and the inner surface is kept at 71 C, . Determine the heat transfer coefficient from inner surface to water under fully developed velocity and temperature flow conditions. Use the following constant thermo-physical properties of water, ρ = 1000kg/m3; μ = 1×10-5 kg/m-s; k = 0.027 W/m-°C; Cp = 4000 J/kg-°C

Water at 20°C flows up a vertical pipe of circular section and internal diameter of 2 inches and height of 12 metres at a volumetric flow rate of 6.7 litres per second. Estimate the change in pressure between the bottom and the top of the pipe if: i. The inner walls of the pipe are assumed to be hydraulically smooth, ii. The pipe is fabricated from cast iron and explain how you solved (ii) above.

In the boiler of a power plant are tubes through which water flows as it is brought from 0.8 MPa, 150°C to 240°C at essentially constant pressure. The total mass flow rate of the water is 100 kg/s. Combustion gases passing over the tubes cool from 1067 to 277 °C at essentially constant pressure. The combustion gases can be modeled as air as an ideal gas. There is no significant heat transfer from the boiler to its surroundings. Assuming steady...

. Inside of a calorimeter (insulated container) is placed 200g of water at 20°C. The lid of the calorimeter is briefly lifted and 50g of lead is added initially at 200°C. What is the thermal equilibrium temperature? (3pts) 10. An object of mass 50kg is pushed in the +x direction with a force of 40N flat along a horizontal surface causing a net acceleration of 0.15m/s2 in the +x direction. What is the coefficient of kinetic friction between the surface...

You mix together two flows of water. The first flow is a saturated liquid at 300 kPa, moving at a rate of 2 kg/s. The second flow is a superheated vapor at 300 kPa and 300 °C, and is moving at a rate of 0.2 kg/s. If the outlet is similarly at 300 kPa, (a) what is the mass flow rate of the outgoing water, (b) what is the temperature of the outgoing water, and (c) What is the rate...

Very cold water (5°C) is heated at atmospheric pressure (1 atm) until saturated vapor is formed. (a) Draw an enthalpy path for the water. (b) Calculate the specific enthalpy change (kJ/mol) for each step in the path, and calculate the total specific enthalpy change (kJ/mol). (c) Compare the total enthalpy change from the enthalpy path to the total enthalpy change using the steam tables (see zyExample in another section). (d) Compute the ratio of latent heat to sensible heat. (e)...

A coaxial cable consists of two long concentric conducting tubes of length l, the inner one of radius a and the outer one of radius b. Assume that the zˆ direction lies along the axis of the cable. A current, I, flows down the inner conductor in the zˆ direction and returns in the outer conductor, where in each case the current is uniformly spread out over the surface. (a) Determine the magnetic field B everywhere. [5] (b) Find the...

Water (cp=4179 J/kg·K) at 30 °C flows on the inside of a steel tube with 25 mm inner diameter and 0.4 mm wall thickness at a flow rate of 0.4 kg/s. The tubes forms inside of a counter flow double pipe heat exchanger. Engine oil at 100 °C flows in the annular space with a flowrate of 0.1 kg/s. The outlet temperature of the oil is 60 °C. The material of the heat exchanger is carbon steel with k=45 W/m·K....
