You are trying to decorate your home with a water fountain, and you are looking for a water pump. Now you need to know the characteristic of the flow provided by this pump. Assume that this water pump can work as it is advertised. It says Can pump 3600 L of water in 1 hour 1.) Find the flow rate provide by this pump. Answer in litre/s. 2.) From the above question, assume that all power is transferred to kinetic energy of the flow. Find the velocity of the flow. Answer in m/s. Hint: Use the result from the above problem to find the mass of water (in kg) circulated by the pump in 1 second. Then the kinetic energy given from the pump to the water flow is 50 J in 1 second. 3.) From the above question, find the surface area of the flow, answer in cm2.
