Hot oil is pumped through a heat exchanger (see figure below) at a flow rate of 0.5 L/s. An inlet manifold equally distributes the oil into 20 parallel, 5-mm-diameter copper tubes that are about 1 m in length. The oil cools down as it flows through the copper tubes. Oil then exits through an outlet manifold. The viscosity of the oil is 250 centipoise and its density is 950 kg/(m^3). Assuming uniform pressure in the manifolds and laminar flow through the tubes, calculate the total head loss (in meters) across those 20 copper tubes.
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.
