Air flows into the atmosphere from a nozzle and strikes a vertical plate as shown in Fig. P5.57. A horizontal force of 12 N is required to hold the plate in place. Determine the reading on the pressure gage. Assume the flow to be incompressible and frictionless. If the flow is supplied by a pump at constant specific heat with Cp = 4.187 KJ/Kg.K, assuming there is a temperature gradient of 23 °C. Calculate the net power needed to satisfy the condition in part (1). 12N Area-0.003 m Area-0.01 m?
