Refrigerant 134a enters an insulated diffuser as a saturated vapor at 100°F with a velocity of 1200 ft/s. The inlet area is 1.4 in?. At the exit, the pressure is 400 lbț/in² and the velocity is negligible. The diffuser operates at steady state and potential energy effects can be neglected. Determine the mass flow rate, in Ib/s, and the exit temperature, in °F.

pure water at 20 c is flowing down an inclined wetted - wall ( making an angle of 60 with horizontal ) at rate of 0.124kg/s.m calculate the film thickness then using a shell momentum balance . calculate the average velocity

As shown in the picture blew, a pump can deliver volume flow rate of    of water through a vertical lift of .  The inlet to the pump is just below the water surface and the discharge is to the atmosphere through a DN50 schedule 40  steel pipe.   The energy loss . (1) Calculate velocity at the exit of point 2__________m/s

Problem-5: In a CD nozzle with a throat area of 0.75 m² of a rocket engine, gas at 7.5 MPa and temperature of 3200 K is in combustion chamber, is expanded fully to (nozzle exit pressure) 10.5 kPa for producing thrust. Assuming flow to be frozen and isentropic, Also, Assume, gamma, y 1.2 and molecular weight, MW = 24 kg/kmol, Assume, universal gas = constant = 8314 J/Kg K mol Determine: (1) the exit Mach number, (2) the maximum exit mass flow rate passing through this nozzle, and (3) the exit area (4) If ambient pressure, i.e. pressure outside nozzle = 10.5 kPa, What is the thrust developed? Fuel Oxidant Combustion zone Mixture of Hot gas at high pressure and Temprature Expansion Through Nozzle High velocity exhaust Liquid Propellant Rocket

Why is the denisty of water included in this equation?
