Question

e Water enters a constant 100 [mon ] I.D. tubes et a bilen at 7 [MPa] and 60000] and leaves the tubes at 6[MPa ] and 400 [°C ] with a speed of 80 [m/s]. Calculate the speed of the water at the tube intet and the inlet volume flow rate. Comment on the mass flow rate in the tube.
please exlain how are you finding the specific volumes for each one to use

VA/v = (VA/v)
