Head Loss given Critical Velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Head Loss = 0.1*((Critical Velocity)^2/(2*Acceleration due to Gravity))
h_f = 0.1*((V_c)^2/(2*g))
This formula uses 3 Variables

Variables Used

Head Loss - (Measured in Meter) - Head Loss is a measure of the reduction in the total head (sum of elevation head, velocity head and pressure head) of the fluid as it moves through a fluid system.
Critical Velocity - (Measured in Meter per Second) - The Critical velocity is the greatest velocity with which a fluid can flow through a given conduit without becoming turbulent.
Acceleration due to Gravity - (Measured in Meter per Square Second) - Acceleration due to Gravity is acceleration gained by an object because of gravitational force.

STEP 1: Convert Input(s) to Base Unit

Critical Velocity: 15 Meter per Second --> 15 Meter per Second No Conversion Required
Acceleration due to Gravity: 9.8 Meter per Square Second --> 9.8 Meter per Square Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h_f = 0.1*((V_c)^2/(2*g)) --> 0.1*((15)^2/(2*9.8))

Evaluating ... ...

h_f = 1.14795918367347

STEP 3: Convert Result to Output's Unit

1.14795918367347 Meter --> No Conversion Required

FINAL ANSWER

1.14795918367347 ≈ 1.147959 Meter <-- Head Loss
