Mechanisms of heat transfer

Heat transfer is an essential discipline in thermal engineering that deals with the transfer, conversion, usability, and creation of heat or thermal energy. Transfer of heat occurs through various mechanisms like conduction, convection, radiation, and change of phases. All these mechanisms have distinct characteristics, but these mechanisms can simultaneously occur in an identical system.

Consider a pumping system used in a cooling water loop. Water is drawn from a tank, which
maintains a height of 2 m of water. It then enters the pump and then passes through the process
heat exchanger, where it is heated. The water is then cooled back to cooling water temperature
using a chiller (another heat exchanger). Finally, water exits the chiller and is circulated back to
the original tank, forming a closed loop. All equipment is at ground level. All pipe in the system is

Consider a condensing heat exchanger operating with two separate fluids, R-134a and the water. Assuming the operating conditions listed in the table below, and that the pressure drop of the fluids are negligible, find the mass flowrate of the water (kg/s) and Q (kW) transferred between the R-134a and the water. m Enters Exits Fluid Water ?

Question 4 A thin-walled double pipe, counter-flow heat exchanger is to be used to cool oil (cp = 2.2 kJ/kg.°C) from 150 °C to 40 °C at a rate of 2.3 kg/s by water (c, = 4.18 kJ/kg.ºC) that enters at 20 °C at a rate of 1.4 kg/s. The diameter of the tube is 13 cm and its length is 60 m. Determine the overall heat transfer coefficient of this heat exchanger using; i. logarithmic mean temperature difference LMTD method, and ii. NTU method.
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?
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.

6. Water is pumped to a storage tank from a pool by a centrifugal pump. The elevation difference between the pool and the storage tank is 60 m. The storage tank and the pool are open to atmosphere. 50 meters of 6 in Sc 40 steel pipe is used between pool and pump. After the pump 6 in Sc 40 pipe with a length of 22 m is suddenly contracted to 4 in Sc 40 pipe, that is 70 m. The flow rate of water is 2.5 m/min and the temperature is 20°C.
