4. The following heat exchanger uses 10 kg/s of hot air to heat and boil liquid water into saturated steam at 500 kPa. (a) Find the steam flow (kg/s) (b) Determine whether the process is allowed by the second law (Answer: It is not!) (c) On the surface, the process looks OK as Tair>Twater at both the inlet and outlet. You should be able to see the problem if you sketch the air and the water temperature profiles as you move left to right through the exchanger. (Hints: The air will be essentially a straight line, while the water will not. For the water, think about what happens when it is changing phase.) This is called a pinch point violation, and it is a very important design consideration in advanced combined cycle systems and in nuclear power plants.

Hello! I'd like help with the following exercise, from Levenspiel's "Engineering Flow and Heat Exchange". Leftover air at 20ºC and 100kPa is driven by a fan through a horizontal galvanized conduit of 1 m in diameter and 10m in length at a speed of 10 m/s. What size motor should be used if its efficiency is 90% and that of the fan is 20%? I'm not sure where to start. My professor hasn't explained much about this subject.
3.36 Both C's in a parallel-flow heat exchanger are equal to 156 W/K, U 327 W/m²K and A = 2 m². The hot fluid enters at 140°C and leaves at 90°C. The cold fluid enters at 40°C. If both C's are halved, what will be the exit temperature of the hot fluid?
Liquid water is heated inside the tubes of a shell and tube heat exchanger as shown in the figure below. The inlet temperature is 30 °C and the outlet temperature is 50 °C. The tube inside and outside diamters are 16 mm and 18 mm respectively. The mass flow rate in each tube is 0.25 kg/s. Refrigerant Gas Water Out Water In Refrigerant Liquid Estimate: a) The average velocity in each tube: b) The Reynolds number in each tube: c) The Nusselt Number of the flow inside each of the tubes: m/s
Air enters a cooler at 1450C and at a pressure of 3 bar and is cooled to 450C by passing through tubes of 10 mm inside diameter surrounded by water which enters the cooler at 150C and exits at 300C. Assuming the heat exchanger is counter flow, find: I) The mean temperature difference. ii) If the air velocity is limited to 6.5 m/s, what is the required length of tube? Neglect the resistance of the tube and assume water side heat transfer coefficient is 232 W/m2K.
3.34 A flow rate of 1.4 kg/s of water enters the tubes of a two-shell-pass, four-tube-pass heat exchanger at 7°C. A flow rate of 0.6 kg/s of liquid ammonia at 100°C is to be cooled to 30°C on the shell side; U = 573 W/m²K. (a) How large must the heat exchanger be? (b) How large must it be if, after some months, a fouling factor of 0.0015 m²K/W is expected to build up in the tubes but we still want to deliver ammonia at 30°C? (c) If we make it large enough to accommodate fouling, to what temperature will it cool the ammonia when it is new? (d) At what temperature does water leave the new, enlarged exchanger? [(d) TH₂0 = 49.9°C.]
3.21 You must cool 78 kg/min of a 60%-by-mass mixture of glycerin in wa- ter from 108°C to 50°C using cooling water available at 7°C. Design a one-shell-pass, two-tube-pass heat exchanger if U = 637 W/m²K. Which side should the water flow through? Explain any design decision you make and report the area, TH₂0out and any other relevant features.

For an inlet valve, the mass flow rate through the valve is 0.44 kg/s. The flow coefficient is 0.62 and the cylinder pressure is 105 kPa.

A heat exchanger is heating water from 50 0 F to 160 0 F using steam on the shell at atmospheric pressure condensing at 212 0 F. If the overall U is 710 BTU/(hr 0 F ft2) and the exchange rate is 9,000,000 BTU/hr, what tube area is needed?
The clean U for an exchanger is 770 BTU/(hr 0 F ft2). Its tube area is 550 ft2. After operating for several months, it is heating water from 40 0F to 150 0F at a flow rate of 200 GPM with a heating fluid on the shell entering at 300 0F and exiting at 170 0 F. Has the overall U decreased significantly? how many 1.0 inch diameter, 20 ft long tubes would it take to equal the 550 ft2 area?
