Consider atmospheric air at 25 degrees Celsius and a velocity at 25 m/s flowing over both surfaces of a 1 meter long flat plate that is maintained at 125 degrees Celsius. Determine the rate of heat transfer per unit width from the plate for values of the critical Reynolds number corresponding to 10^5, 5x 10^5, and 10^6.

Water is pumped from a lake at ambient pressure and temperature to an elevation of 15 m through a pipe of 2-cm diameter galvanized iron at a flow rate of 0.00366 m3 /s. Assume the discharge is to open atmosphere. The pipe is 70 m long and has 2- 90o ..
To determine the heat transfer characteristics of a cylinder under cross flow conditions when the cylinder is isolated.
A force of F= (-2i+8j-6k)N is applied to an object that is constrained to move in the direction u=0.5571i+0.4481j-0.6992k. If the object has a total displacement of 10 meters in the direction of u, calculate the work done on the object by the force.
