I am having trouble with this problem.

Water is pumped from the large tank shown in the figure. The loss in the piping is equal to 2V² – note that this loss is in units of m²/s² = J/kg. The pump power is \( \dot{W}_{pump} = 40,000 \, Q - 400,000 Q^3 \), where \( \dot{W}_{pump} \) is in Watts and Q is in m³/s.

a.) Determine the flow rate.
b.) Determine the pressure increase across the pump.
c.) Determine the flow rate if the loss was the same, but the pump is not installed.

**Diagram Explanation:**

- The diagram shows a large tank with water at a certain level.
- Water is drawn from the bottom of this tank and moves through a pipe with an area of 0.01 m².
- The pipe has a pump to assist in moving the water.
- The height from the water surface in the tank to the pipe inlet is labeled as 4 meters.
- Arrows indicate the direction of water flow, and the symbol Q represents the flow rate.
