What is the total static head in a pump system with specific liquid levels and friction losses?
The total static head in this scenario is 14.2 meters. This value represents the pressure exerted by the liquid due to the difference in liquid levels and the friction losses in the suction and discharge lines. To calculate the total static head in this scenario, we need to consider the difference in liquid levels between the suction and discharge points of the pump, as well as the friction losses in the suction and discharge lines.
Understanding Total Static Head Calculation
The Calculation Steps:
1. The liquid level difference between the suction and discharge points is the sum of the liquid level below the pump suction (3.8 m) and the liquid level above the pump discharge (6.4 m):
Total liquid level difference = 3.8 m + 6.4 m = 10.2 m.
2. We also need to account for the friction losses in the suction and discharge lines. The friction loss in the suction line is given as 0.2 m, and the friction loss in the discharge line is given as 3.8 m.
Total friction loss = 0.2 m + 3.8 m = 4 m.
3. Therefore, the total static head is the sum of the liquid level difference and the friction losses:
Total static head = Total liquid level difference + Total friction loss
= 10.2 m + 4 m
= 14.2 m.
So, the total static head in this scenario is 14.2 meters. This value represents the pressure exerted by the liquid due to the difference in liquid levels and the friction losses in the suction and discharge lines.
