Air at atmospheric pressure and a temperature of 25 °c is in parallel flow at a velocity of 5 m/s over a 1.0-m-long flat plate that is heated from below with a uniform heat flux of 1250 w/m2. assume the flow is fully turbulent over the length of the plate. (a) calculate the plate surface temperature, t,(l), and the local convection coefficient, h (l), at the trailing edge, x=l. (b) calculate the average temperature of the plate sur- face, t. (c) plot the variation of the surface temperature, t(x) and the convection coefficient, h,(x), with distance on the same graph. explain the key features of these distributions.

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.
