Calculation of Total Head at a Point in Water
Given Data:
- Pressure at the point = 196.2 KN/m2
- Velocity at the point = 0.5 m/s
- Point is 5m above the datum
Formula to Calculate Total Head:
The total head at a point in water is given by the sum of three heads:
Total Head = Pressure Head + Kinetic Head + Elevation Head
Calculation:
- Pressure Head = (Pressure at the point)/(Density of water x Acceleration due to gravity)
- Kinetic Head = (Velocity at the point)^2/(2 x Acceleration due to gravity)
- Elevation Head = Height of the point above the datum = 5m
- Total Head = Pressure Head + Kinetic Head + Elevation Head
Using the above formula, Pressure Head = (196.2 KN/m2)/(1000 kg/m3 x 9.81 m/s2) = 0.02 m
Using the above formula, Kinetic Head = (0.5 m/s)^2/(2 x 9.81 m/s2) = 0.01 m
Substituting the above values, Total Head = 0.02 m + 0.01 m + 5m = 5.03 m
Result:
The total head at the given point in water is 5.03m.
