Water at 20degc flows through a 5 cm id plastic pipe 100 m

Question

Water at 20°C flows through a 5 cm I.D. plastic pipe 100 m long. The velocity of the water at the inlet of the pipe is 4 m/s. The outlet of the pipe discharges to atmosphere and is 35 m above the inlet.

Determine the specific potential energy (in SI units).

Data:

Density of Water at 20°C = 1000 kg/m³

Viscosity of Water at 20°C = 1cP

Atmospheric pressure = 101 kPa

Gravitational acceleration = 9.8 m/s²

This question accepts answer with one decimal place.
