Calculation of Specific Speed of Double Suction Centrifugal Pump
Given:
Q = 1.5 m^3/s
H = 16m
N = 750 rpm
Step 1: Calculate the specific speed (N_s) of the double suction centrifugal pump using the following formula:
N_s = N * Q^0.5 / H^0.75
Step 2: Substitute the given values in the formula:
N_s = 750 * (1.5)^0.5 / (16)^0.75
Step 3: Solve for N_s:
N_s = 471.9
Therefore, the specific speed of the double suction centrifugal pump is 471.9.
Explanation:
The specific speed of a pump is a dimensionless number that is used to characterize its performance. It is defined as the speed of a geometrically similar pump that would deliver unit flow rate against unit head. In other words, it is a measure of the relative proportions of flow rate, head, and speed of a pump.
In this case, we have a double suction centrifugal pump that delivers 1.5 m^3/s of water against a net head of 16m at a speed of 750 rpm. By using the specific speed formula, we can calculate the specific speed of the pump, which is a measure of its performance.
The specific speed of the double suction centrifugal pump is 471.9, which indicates that it is a relatively low-speed pump with a moderate flow rate and head. This information can be useful in selecting and designing pumps for specific applications.
