A pump moves water horizontally at a rate of (0.02 mathrm{~m}^{3} / mathrm{s}). Upstream of the pump

Question:

A pump moves water horizontally at a rate of \(0.02 \mathrm{~m}^{3} / \mathrm{s}\). Upstream of the pump where the pipe diameter is \(90 \mathrm{~mm}\), the pressure is \(120 \mathrm{kPa}\). Downstream of the pump where the pipe diameter is \(30 \mathrm{~mm}\), the pressure is \(400 \mathrm{kPa}\). If the loss in energy across the pump due to fluid friction effects is \(170 \mathrm{~N} \cdot \mathrm{m} / \mathrm{kg}\), determine the hydraulic efficiency of the pump.
