Forced-convection heat transfer in flow between parallel plates (Fig. 10B.7). A viscous fl uid with temperature-independent physical properties is in fully developed laminar flow be- tween two flat surfaces placed a distance 2B apart. For 20 the fluid temperature is uniform at both walls. Find the temper- ature distribution T(x, z) for large z. (a) Make a shell energy balance to obtain the differential equation for Tx, 2). Then discard the viscous dissipation term and the axial heat conduction term. Steel plate 2500°F 100°F Fig. 10B.6. A composite furnace wall. Fig. 10B.7.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
