2. An engineer doing an audit finds that liquid water from a process enters the cooling tower at 80 F and with a volumetric flow of 25 gpm and exits at 70 F. Air enters the tower at 80 F and relative humidity of 70% . Air exits the tower at 90 F and 90% relative humidity. The tower does not use make up water.

A liquid mixture containing ethanol (55.0wt%) and the balance water enters a separation process unit at a rate of 90.5 kg/s. A technician draws samples of the two product streams leaving the separator and analyzes them with a gas chromatograph, obtaining values of 86.2wt% ethanol (product stream 1) and 10.9% ethanol (product stream 2). The technician then reads a manometer attached to an orifice meter mounted in the pipe carrying product stream 1, converts the reading to a volumetric flow...

In an industrial cooling process, water is circulated through a system. If water is pumped with a speed of 4.00 m/s under a pressure of 6.70 × 105 Pa from the first floor through a 3.70-cm diameter pipe, what will be the pressure on the next floor 3.90 m above in a pipe with a diameter of 2.00 cm?

A sample of cooling liquid containing ethylene glycol and water is brought to your lab. The cooling tower contains 2,500 tons of this coolant to keep the chillers at an oil refinery working properly. It is critical that the concentration of the ethylene glycol be maintained at a concentration of 44.0±0.5%(w/w), to prevent freezing and transfer the heat properly. Since it’s late and an unexpected cold front has the plant manager worried, you decide to use the refractometer to run...

Distillation is one of the important unit operations in chemical process. It is a process of separating a component from its liquid mixture, which involves heating and cooling process.

Distillation is one of the important unit operations in chemical process. It is a process of separating a component from its liquid mixture, which involves heating and cooling process. There are various types of distillation methods, such as simple distillation, fractional distillation, steam distillation and vacuum distillation. Based on the above description, answer the following questions: Question 1 Identify three (3) factors to be considered in selecting a suitable distillation process. Question 2 Distillation may cause incomplete separation or partial separation of a component in...

1.Water samples were taken from water used for cooling as it was being discharged from a power plant into a river. It has been determined that as long as the mean temperature of the discharged water is at most 150 F, there will be no negative impact on the river's ecosystem. To investigate whether a plant is in compliance with regulations that prohibit a mean discharge water temperature above 150 F, researchers took 50 water samples at randomly selected times...

Saturated liquid water at 1 MPa enters a D = 5 cm pipe at a rate...

Saturated liquid water at 1 MPa enters a D = 5 cm pipe at a rate of m(dot) = 2 kg/s. Heat is transferred to the water at a rate of Q(dot) = 5000 kW. The exit is at 1 MPa pressure. (a) Neglecting kinetic energy, calculate the temperature at the pipe exit. (ans = 400◦C) (b) Using your answer in a), calculate the exit velocity of the water. (ans = 312 m/s) (c) Based upon your answer, should kinetic...

Gas Transport: A trout swims from its normal cold water habitat into a warm water cooling pond. Clearly this is a dangerous situation. Heat shock isn’t an issue. It isn’t that warm. But it is still quite a bit warmer than the cold, fast, highly mixed stream that the trout was in before. So, what about the pond water makes it dangerous? In terms of the trout’s blood will the trout be able to extract what it needs from the...

Cooling water (T= 20 C) is pumped from a reservoir to rock drills on a construction job using the pipe system With Diameter D = 10 cm. The flow rate must be 130 m3/h and water must leave the spray nozzle at 30 m/s. Nozzle discharge at the 100 m above reservoir (a) Calculate the minimum pressure needed at the pump outlet. (b) Estimate the required power input if the pump efficiency is 70 percent. know that, K 1 =...
