Fluid Mechanics
Subtopic: Continuity equation, kinematics and dynamics of flow
Question Statement:
Water of density rho = 1000 kg/m^3 flows through a hydraulic test section #35 related to Continuity equation, kinematics and dynamics of flow. If head loss across length L = 10 m is h_f = 1.3 m under g = 9.81 m/s^2, the pressure drop in kPa (Delta P = rho * g * h_f / 1000) is approx:
Answer Key:
12.75
Step-by-Step Solution & Explanation
Pressure drop Delta P = 1000 * 9.81 * h_f / 1000 = 12.75 kPa.
