An incompressible, Newtonian fluid flows downwards between two vertical parallel plates that are a distance 2h away from each other. The flow is fully developed(i. e. steady) and the entirety of the velocity is the in vertical direction and due to gravity. Assuming there is no pressure gradient, solve for this velocity, w, as a function of z.

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.

Wiy doeres rere okhn a pump whon working betwon the same pressure range?
