Project Assignment A Stainless-Steel Plate Heat Exchanger Requires a Pump. A performance test for water and ethylene glycol mixture fluid at 50%/50% mixing ratio is done on a stainless-steel plate heat exchanger. The 15 L mixture of Water (50%)/Ethylene Glycol (50%) is the hot side fluid and water from the tap is used as the cold side fluid. The total heat transfer area of over 600 2 , the length of the plate is 175 mm, the width of the plate is 60 mm, the thickness of the plate is 18 mm and the gap between the parallel plates is 2.2 mm. The flow rates chosen for the performance test are 1 L/min, 2 L/min, 3 L/min, 4 L/min and 5 L/min. The plate heat exchanger requires the us
