Here we will see the relationship between the pump size (diameter) with the pump head and discharge. Reducing the pump size (diameter) results in a decrease in both the pump discharge (the volume of fluid expelled per unit of time) and the pump head (the energy imparted to the fluid). This happens because a smaller (pump) diameter often leads to increased fluid velocity and more resistance, causing a drop in both discharge and head. This is reason for the decrease in both head and discharge on using a smaller pump. On using a smaller pump the Pump head will decrease and pump discharge will also decrease.

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

Question

For the following pump-pipe system below, how will the discharge and pump head change if a smaller pump in the same family is used to replace the current pump? Increase or decrease?

**Diagram Explanation**

The image displays a schematic of a pump-pipe system along with a graph illustrating the relationship between head and discharge. The diagram includes the following components and elements:

- **Schematic Diagram**:
- The system shows a pump labelled as "P" between two elevation points, \( E_A \) and \( E_B \).
- There is a static head \( H_s \).

- **Graph Details**:
- **Axes**: The vertical axis represents the head in feet, and the horizontal axis represents the discharge in cubic feet per second (cfs).
- **Curves**:
- The **system head curve** trends upward, indicating the head required by the system at various discharges.
- **Pump characteristics curve** trends downward, representing the performance of the pump (head vs. discharge).
- The **intersection point** between the system head curve and the pump characteristics curve indicates the operating point of the pump, showing the head and discharge where the pump and system meet the performance requirements.

**Options:**
- The options provided ask about the change in pump head and discharge with the introduction of a smaller pump:
1. Pump head will decrease; discharge will decrease.
2. Pump head will increase; discharge will increase.
3. Pump head will increase; discharge will increase.
4. Pump head will decrease; discharge will increase.

Each option explores different potential outcomes of replacing the current pump with a smaller one in terms of pump head and discharge performance.
