Water enters a uniformly heated vertical tube of diameter 2.5 cm and length 4.5 m. Total heat applied to the tube is 650 kW. Inlet pressure, temperature, and mass flow rate of water are given as 100 bar, 285 C, and 1.5 kg/s, respectively. Find the pre-heating length, exit quality, and various pressure differentials terms.
thermodynamics
Two products enter an indirect contact heat exchanger that uses steam for heating. The first product which
contains 12% solids enters at the rate of 3 kg/hr and at 10 °C. The second stream which contains 20%
solids enters at the rate of 4 kg/hr and at 20 °C. Saturated steam at 150 °C (hL = 2745.9 kJ/kg, hv = 632.25
k.J/kg) enters the heat exchanger at 0.5 kg/hr with a quality of 95% and exits at 10% quality. The resulting
mixture enters an indirect contact cooler. Water enters the indirect contact cooler at a temperature of 10 °C
and exits at 25 °C. Two product streams exit the cooler. The first stream contains 24% solids and exits at
2 kg/hr and at 10 °C, while the second stream exits at 12 °C. The specific heat of the solids is 3500 J/kg K
and that of water is 4180 J/kg K. Complete/label the process diagram and determine the following:
a. Specific heat of each stream
b. Enthalpy of entering and exiting steam
c. Temperature of the mixture exiting the indirect contact heat exchanger,…

- A heat exchanger as shown in Figure 1 is used for an air conditioning system that is working through chilled water. Hot air at 1 bar and 42 °C enters the heat exchanger at a volume flowrate of 1 m /s leaving at 21 °C.
