Manometric Head using Total Head at Outlet and Inlet of Pump Solution

Follow our step by step solution on how to calculate Manometric Head using Total Head at Outlet and Inlet of Pump?

FIRST Step Consider the formula

H m = ((\frac{P 2}{w}) + (\frac{{V d}^{2}}{2 \cdot [g]}) + Z 2) - ((\frac{P 1}{w}) + (\frac{{V s}^{2}}{2 \cdot [g]}) + Z 1)

Next Step Substitute values of Variables

∴

H m = ((\frac{0.14MPa}{9.81kN/m³}) + (\frac{{5.23m/s}^{2}}{2 \cdot [g]}) + 19.9m) - ((\frac{0.07MPa}{9.81kN/m³}) + (\frac{{2.1m/s}^{2}}{2 \cdot [g]}) + 2.9m)

Next Step Substitute values of Constants

∴

H m = ((\frac{0.14MPa}{9.81kN/m³}) + (\frac{{5.23m/s}^{2}}{2 \cdot 9.8066m/s²}) + 19.9m) - ((\frac{0.07MPa}{9.81kN/m³}) + (\frac{{2.1m/s}^{2}}{2 \cdot 9.8066m/s²}) + 2.9m)

Next Step Convert Units

∴

H m = ((\frac{140000Pa}{9810N/m³}) + (\frac{{5.23m/s}^{2}}{2 \cdot 9.8066m/s²}) + 19.9m) - ((\frac{70000Pa}{9810N/m³}) + (\frac{{2.1m/s}^{2}}{2 \cdot 9.8066m/s²}) + 2.9m)

Next Step Prepare to Evaluate

∴

H m = ((\frac{140000}{9810}) + (\frac{{5.23}^{2}}{2 \cdot 9.8066}) + 19.9) - ((\frac{70000}{9810}) + (\frac{{2.1}^{2}}{2 \cdot 9.8066}) + 2.9)

Next Step Evaluate

∴

H m = 25.305338298052m

LAST Step Rounding Answer

∴

H m = 25.3053m
