Calculate the power required by the pump shown in the figure. It is desired to pump methyl alcohol at 25 °C (? = 789 kg/m3, ? = 5.60 x 10-4 Pa·s) with a flow rate of 54 m3/h. The suction line is a standard DN 100 Schema 40 commercial steel pipe, 15 m long. The total length of the commercial steel pipe DN 50 Scheme 40 in the discharge line is 200 m. Assume that the entrance to the warehouse is through a sharp-edged entrance and that the elbows are standard. The valve is a fully open globe valve.
