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.

Modern high speed trains do not have perpendicular expansion gaps where rails are joined end-to-end any more they are mostly welded together but what might happen if there was a spell of particularly hot weather that causes inspection of the tracks?
