The reynolds number, pvd/u, is a very important parameter in fluid mechanics. verify that the reynolds number isdimensionless, using both the flt system and the mltsystem for basic dimensions, and determine its value for ethylalcohol flowing at a velocity of 3 m/s through a 2-in.-diameter pipe.

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.
