A subsonic diffuser flow is steady and adiabatic with inlet Mach number M1 = 0.6. Total pressure loss in the diffuser is 2% of the inlet total pressure, i. e., pt2/ pt1 = 0.98. The diffuser area ratio is A2/ A1 = 1.50. Assuming that the flow in the diffuser has a uniform exit flow, calculate the exit Mach number M2 the static pressure recovery in the diffuser CPR the (internal) force acting on the diffuser, i. e., Fx, wall, nondimensionalized by the inlet static pressure and ar

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

The drive force for diffusion is 7 fick's first law can be used to solve the non-steady state diffusion. a)-true b)-false

Air flows over a heated plate àt a velocity of 50m/s. the local skin factor coefficient at a point on a plate is 0.004. estimate the local heat transfer coefficient at this point.the following property data for air are given: density = 0.88kg/m3 , viscosity 2.286 x 10 ^-5 kgm/s , k = 0.035w/mk ,cp = 1.001kj/kgk. use colburn reynolds analogy.
