Deionized water flows through the inner tube of 30-mm diameter in a thin-walled concentric tube heat exchanger of 0.19-m length . hot process water at 95 c in the annulus formed with the outer tube of 60-mm diameter to 50c . the deionized water is to be heated from 40 to 60 c at a flow rate of 5 kg/s. The thermo physical properties of the fluids are from table (A)considering a paralle-flow configuration of the heat exchanger , determine the flow rate required for the hot process what
(B) determine the overall heat transfer coefficient required for the conditions of part a
(C) considering a counter flow configuration, determine rate of heat transfer
