Transcribed Image Text:

Gas at atmospheric pressure and 40°C flows with a velocity is 5m/s over a 2m long flat plate whose surface is kept at a uniform temperature of 120°C. The average heat transfer coefficient (in W/m²°C) over the 2m length of the plate if the properties of gas at mean film temperature are Kinematic viscosity = 2.107 × 105 m²/s, X Thermal conductivity = 0.03025 W/mK, Prandtl number = 0.6965.
