Q$1$ CHAPTER $7$: SERIES AND PARALLEL PIPING SYSTEM

Calculate the power supplied to the pump shown in the figure below if its efficiency is $76\%.$ Methyl alcohol at $25C$ is flowing at the rate of $54\frac{m^3}{h}r.$ The suction line is a standard DN $100$ Schedule $40$ steel pipe, $15$ m long. The total length of DN $50$ Schedule $40$ steel pipe in the discharge line is $200$ m $.$ Assume that the entrance from reservoir $1$ is through a square$-$edged inlet and that the elbows are standard. The valve is a fully open globe valve.
