Q5. What is the formula of centrifugal pump head
Ans. 
The formula for centrifugal pump head is H = (Q * SG) / (3.14 * D^2 * 2.31)
• Head (H) is calculated using the flow rate (Q), specific gravity (SG), and diameter of the impeller (D)

• The formula is derived from the basic equation for head in a centrifugal pump

• Example: H = (100 gpm * 1.0) / (3.14 * 0.5^2 * 2.31) = 45.75 ft
