In a solar hot water heater, oil is used Using the\"effectiveness - NTU\" function in the EES Heat Transfer options,calculate the length of pipe and the exit temperature of the waterfor the following heat exchanger configurations: counter-flow,parallalel-flow, and a 2-pass shell and tube HX. Use the operatingconditions listed below to rank the 3 HX configurations based oneffectiveness.
Fluids (water: Cp=4.189 kJ/kg-K, oil: Cp=1.75 kJ/kg-K)
mass flow rate (water: 0.5 kg/s, oil: 0.1 kg/s)
pipe diameter = 1 inch
overall heat transfer coefficient = 75 W/m2-K
Ti_water=25 C Ti_oil=120 C To_oil=75 C
Provide a schematic for each of these HX configurations
