Question
A hydraulic fluid preheater consists of a single tube with a diameter of \( D = 0.5 \, \text{in} \) and a length of \( L = 5 \, \text{m} \). The tube surface is maintained at \( T_s = 200^\circ \text{F} \) by hot combustion gases flowing past the outside surface. The hydraulic fluid enters at \( T_o = 80^\circ \text{F} \) and a mass flow rate of 370 lb\(_m\)/h. (a) Determine the convection heat transfer coefficient for the hydraulic fluid flowing through the tube. (b) Determine the hydraulic fluid exit temperature. (c) Determine the heat transfer rate to the hydraulic fluid. (d) Determine the power required to pump the hydraulic fluid through the tube.
