Water is to be pumped from a lake to a tank uphill that is open to the atmoshpere. The flow rate of water is 10 liters per minute and the flow channel is 10 cm^2 in area. A pump capable of delivering 8 hp = (Work) is availible. the friction loss F (KJ/s) equals 0.5 L, where L is the length of the pipe in meters. Calculate the maximum elevation z of the ranger station if the pipe rises at an angle of 30 degrees.
