Manometric head given head imparted by impeller and loss of head in pump Solution

Follow our step by step solution on how to calculate Manometric head given head imparted by impeller and loss of head in pump?

FIRST Step Consider the formula

H m = (V w2 \cdot \frac{u 2}{[g]}) - (h Li + h Lc)

Next Step Substitute values of Variables

∴

H m = (16m/s \cdot \frac{19m/s}{[g]}) - (3.6m + 2.4m)

Next Step Substitute values of Constants

∴

H m = (16m/s \cdot \frac{19m/s}{9.8066m/s²}) - (3.6m + 2.4m)

Next Step Prepare to Evaluate

∴

H m = (16 \cdot \frac{19}{9.8066}) - (3.6 + 2.4)

Next Step Evaluate

∴

H m = 24.999372874529m

LAST Step Rounding Answer

∴

H m = 24.9994m
