An oil cooler with a mass flow rate 0.5 kg/s is used to cool lubricating oil from 140°C to 60°C in a counter-flow double pipe heat exchanger. The cooling water at 15°C and 0.3 kg/s enters the inner tube (k=50W/mK) having 29mm inner and 32mm outer diameter. If the oil side heat transfer coefficient based on the outer surface of the inner tube is 40 W/m2K and the cooling water has a specific heat of 4217 J/kgK, calculate: Outlet temperature of the cooling water Required tube length Could you please write the solution in detail?
Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
