Question 24

A water service enters a structure at a geodetic elevation of 724.5 m with a pressure of 490 kPa. What is the water pressure if the height of the water exit is 729.3 metres?

a) 745 kPa
b) 538 kPa
c) 235 kPa
d) 442 kPa

Answer 24

d) 442 kPa

The water pressure at the exit can be calculated by subtracting the
pressure loss due to elevation gain from the initial pressure. The elevation gain is
729.3m - 724.5m = 4.8m. The pressure loss is 4.8m x 9.81kPa/m = 47.1kPa.
Therefore, the final pressure is 490kPa - 47.1kPa = 442.9kPa, which is
approximately 443kPa.
