I need to solve the question in half an hour.
Q1: Find the average convection coefficient and the average local convection coefficient for experimental results for flow over a flat plate were found to fit the relation:
Where, a is a coefficient (W/m^3/2 K).
Q2: A rectangular plate (100*50 cm) - Oxygen flows over that at 30°C at pressure 1 atm. The velocity is 40 m/s. The plate temperature is indicated as a constant temperature of 124°C. Estimate the convection heat transfer coefficient and the total heat that is lost.
