Question 1 The compressed air at 150 kPa is used in the cooling process of a hot flat plate. The airstream passing through a square flat plate as shown in Figure 1. Free-stream temperature is 25°C flows over a square flat plate at a velocity of 45 m/s. Given the Reynolds number is 4.5 × 10° at the edge of the plate. Determine: (a) Film temperature. (b) Thermal conductivity, dynamic viscosity, kinematic viscosity and Prandtl number. (c) The density of air at 150 kPa. (d) Average heat transfer coefficient. (e) Heat Transfer for the plate maintained at 57C.
