In a sudden contraction, the velocity head changes from 0.5 m to 1.25 ...
Given data:
Velocity head at inlet, H₁ = 0.5 m
Velocity head at outlet, H₂ = 1.25 m
Coefficient of contraction, C_c = 0.66

To calculate: Head loss in the contraction

Formula used:
Head loss (H_L) = H₁ - H₂/C_c²

Calculation:
Substituting the given values in the formula, we get
H_L = 0.5 - 1.25/0.66²
H_L = 0.332 m

Therefore, the head loss in the sudden contraction is 0.332 m.
