FM-100.09 E

Teaching Experimental Applications

EXPERIMENT 1: Single Pump Head-Flow Relationship (Characteristic curve)

Description: To Show the relationship between total head and the flow-rate output supplied by the pump.

EXPERIMENT 2 : Finding The Single Pump Specific Speed

Description: To learn how to extract the value of Specific Speed Of a pump so that it can be used characterize the type of impeller in a pump.

EXPERIMENT 3: Finding Single Pump Efficiency
Description: The experiment is designed for students to learn how to find the efficiency of pumps and evaluate factors on which the efficiency depends.

EXPERIMENT 4: Finding the Single Pump NPSH (A) Value

Description: Purpose of experiment is the students should learn the basic concept of NPSH and NPSHr.

EXPERIMENT 5: Plotting the Serial Combo Pump Characteristic Curve
Description: This experiment is designed to 1. Visually Observe the effect of Series Combination on Pressure and then on flow.

EXPERIMENT 6: Drawing the Parallel Combo Pump Characteristic Curve

Description: The new curve can be found experimentally by connecting two identical parallel pumps in series.
