Subtopic: Hydrostatic pressure and its measurement

Question Statement:

Water of density rho = 1000 kg/m^3 flows through a hydraulic test section #26 related to Hydrostatic pressure and its measurement. If head loss across length L = 10 m is h_f = 0.5 m under g = 9.81 m/s^2, the pressure drop in kPa (Delta P = rho * g * h_f / 1000) is approx:

Answer Key:

4.91

Step-by-Step Solution & Explanation

Pressure drop Delta P = 1000 * 9.81 * h_f / 1000 = 4.91 kPa.
