Heat-Exchangers-and-Mass-Transfer

A counter flow heat exchanger is used to col 2000 kg/hr of oil (c p = 2.5 k J/kg K) from 105 degree Celsius to 30 degree Celsius by use of water entering at 15 degree Celsius. If overall heat transfer coefficient is expected to be 1.5 k W/m2 K, find out water flow rate. Presume that exit temperature of water is not to exceed 80 degree Celsius

Consider the above problem, make calculations for maximum possible effectiveness if the fluid flow conforms to counter flow arrangement

A counter flow heat exchanger is used to col 2000 kg/hr of oil (c p = 2.5 k J/kg K) from 105 degree Celsius to 30 degree Celsius by use of water entering at 15 degree Celsius. If overall heat transfer coefficient is expected to be 1.5 k W/m2 K, find out water flow rate. Presume that exit temperature of water is not to exceed 80 degree Celsius

A cold fluid (specific heat 2.95 k J/kg K) at 10 kg/min is to be heated from 25 degree Celsius to 55 degree Celsius in a heat exchanger. The task is accomplished by extracting heat from hot water (specific heat 4.186 k J /kg K) available at mass flow rate 5 kg/min and inlet temperature 85 degree Celsius. Identify the type of arrangement of the heat exchanger
