WebThe flow work is the work done on the system when entering material is pushed into it or the work done by the system when the system pushes the material out of the system. In other words, the flow work is the energy required to make a room or space for the material by pushing environment and establishing its volume and pressure. So the work ... Webm = mass flow rate (kg/s) Q = volume flow rate (m 3 /s) Example - Pumping Water. Water is pumped from an open tank at level zero to an open tank at level 10 ft. The pump adds four horse powers to the water when pumping 2 ft 3 /s. Since v in = v out = 0, p in = p out = 0 and h in = 0 - equation (6) can be modified to: h shaft = h out + h loss. or
