At room temperature, the water in the storage tank is pumped up to the top of the absorption tower at a flow rate of 10.8 m3/h. The point at which the upward water is discharged is in the atmosphere at a height of 5 m from the surface of the water storage tank. Calculate the friction loss during transportation [J/kg] when the inner diameter of the transport pipe is 50mm, the efficiency of the pump is 50% and the pump work (Wp) is 150J/kg (=m2/s2). However, it is assumed that the area of the liquid level of the water storage tank is very large compared to the cross-sectional area of the transport pipe outlet.
