Find out the local convection coefficient for a flow over a flat plate at a distance of 0.2 m from the leading edge. The fluid is water at 60°C with a velocity of 2 m/s. The plate maintains a uniform temperature. Assume the film temperature to be 40°C. 6442-9 Is the flat plate losing heat to or gaining heat from the water flow? Justify.

Oilflow in a journal bearing can be treated as parallel flow betweentwo large isothermal plates with one plate moving at a constant velocityof 12 m/s and the other stationary. Consider such a flow with a uniformspacing of 0.7 mm between the plates. The temperature of the upperand lower plates are 47°C and 17°C, respectively. By simplifying andsolving the continuity, momentum, and energy equations, determine:(a) thevelocity andtemperature distributionsin the oil.(b ) the maximum temperature and where itoccurs.(The location ofmaximum temperature is determined bysetting dT/dy=0).(c) the heat flux from the oil to each plate

Air stream at 1 atm flows with a velocity of 2 m/s, in parallel over a 3 m long square flat plate, placed on ground, where there is an unheated starting length of 1 m. The air stream has a temperature of 20 °C and the heated section of the flat plate is maintained at a constant temperature of 80 °C. Determine the local heat transfer coefficient at trailing edge and average convection heat transfer coefficient for the heated section. Also calculate the heat loss by convection. Determine the average friction coefficient and wall shear stress and drag force.
