Fluid Mechanics

Subtopic: Flow through orifices, weirs and notches

Question Statement:

Water of density rho = 1000 kg/m^3 flows through a hydraulic test section #14 related to Flow through orifices, weirs and notches. If head loss across length L = 10 m is h_f = 1.1 m under g = 9.81 m/s^2, the pressure drop in kPa (Delta P = rho * g * h_f / 1000) is approx:

Answer Key:

10.79

Step-by-Step Solution & Explanation

Pressure drop Delta P = 1000 * 9.81 * h_f / 1000 = 10.79 kPa.
