During an experiment, a plate heat exchanger that is used to transfer heat from a hot-water stream to a cold-water stream is tested, and the following measurements are taken:
Hot Water Stream Cold Water Stream
Inlet temperature,°C 38.9 14.3
Outlet temperature, °C 27.0 19.8
Volume flow rate, L/min 2.5 4.5
The heat transfer area is calculated to be 0.056 m2.
(a) Calculate the rate of heat transfer to the cold water.
(b) Calculate the overall heat transfer coefficient.
(с) Determine if the heat exchanger is truly adiabatic. If not, determine the fraction of heat loss and calculate the heat transfer efficiency.
(d) Determine the effectiveness and the NTU values of the heat exchanger.
Also, discuss if the measured values are reasonable.

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
