A plate with negligible thickness of 50 cm and a length of 100 cm is exposed to 2 different air flows in the same direction from its lower and upper surface along its length. The speed of the air flowing from the upper surface of the plate is 3600 m / min and its temperature is 473 K, the temperature of the air flowing from the lower surface is 298 K and its speed is 600 m / min. Calculate the total heat exchange between both fluids. (Assume the initial temperature of the plate is 160⁰C.)

The local atmospheric pressure in Denver, Colorado (elevation 1610 m), is 83.4 kPa. Air at this pressure and 20°C flows with a velocity of 8 m/s over a 1.5 m * 6 m flat plate whose temperature is 140°C.

In a geothermal power plant, the used geothermal water at 80°C enters a 15-cm-diameter and 400-m-long uninsulated pipe at a rate of 8.5 kg/s and leaves at 70°C before being reinjected back to the ground. Windy air at 15°C flows normal to the pipe. Disregarding radiation, determine the average wind velocity in km/h.
Water at 15°C is to be heated to 65°C by passing it over a bank of resistance heating rods 4 m long and 1 cm in diameter which are maintained at 90°C.

A 2.4-m-diameter tank is initially filled with water 4 m above the center of a sharp-edged 10-cm-diameter orifice. The tank water surface is open to the atmosphere, and the orifice drains to the atmosphere. Neglecting the effect of the kinetic energy correction factor, calculate (a) the initial velocity from the tank and (b) the time required to empty the tank. Does the loss coefficient of the orifice cause a significant increase in the draining time of the tank?
