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

A single pump and system have characteristics as shown on the graph below. Based on this information, estimate:

(a) The flow rate with one pump online.
(b) The flow rate if the pump’s speed is doubled.
(c) The flow rate of two identical pumps operating in parallel (original pump speeds).
(d) The flow rate of two identical pumps operating in series (original pump speed).
(e) The flow rate if the system’s static head doubles.
(f) Pump head (original system) if a valve is opened until the flow rate is 5.5 cfs.

### Graph Explanation:

The graph below illustrates the relationship between flow rate and head for a pump system.

- **X-axis:** Represents the flow rate in cubic feet per second (cfs), ranging from 0 to 12.
- **Y-axis:** Represents the head in feet, ranging from 0 to 350.

Two curves are shown:

1. **Blue Curve (hp(req)):** This indicates the required pump head as a function of flow rate. It starts at 0 and increases sharply, following an exponential pattern.
2. **Red Curve (hp(avail)):** This shows the available pump head. It begins around 50 feet and initially remains constant before gradually decreasing after a certain point.

These curves help analyze the system's performance under different conditions as mentioned in the tasks.

You and a friend plan to throw one end of a hose over a tall fence to siphon water from your side to the other side. Your friend says it doesn't matter how high the fence is, it will always work as long as your end of the hose is higher than the other side. However, you remind him that isn't actually true. What is the potential problem and about how high can the fence be (in meters) before it becomes an issue?
