Please help and fully explain

5. You are co-worker of Homer Simpson at the Springfield Nuclear Power Plant. One of your responsibilities is to maintain the water flow into the coolant tank that keeps the nuclear reactor from melting down. The water flows through a pipe with an initial radius of 0.50m, and a final radius of 1.0m. The density of the water is 1000 kg/m3. a. What initial speed must the water have if the final speed is 2.0 m/s? b. The pipe receives water from a pump located at the bottom of the ship and has to move the water up 25m to reach the coolant tank. If the final water pressure is 1.01 x 105 N/m2, what must be the initial water pressure that the pump provides? Include a picture with labels.
