Forced air with temperature of 10 °C and velocity of 15 m/s flows on a heated flat plate (200 cm long and 20 cm width) at surface temperature of 100 °C. The thermal conductivity, kinematic viscosity, density, and Prandtl number of the air are k = 0.026 W/m. C, ν = 1.6 x 10-5 m2/s, rho = 1.12 and Pr = 0.71, respectively. What is the heat transfer rate of the entire surface?

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
