A large tank open to the atmosphere is filled with water to a height of 5 m from the outlet tap. A tap near the bottom of the tank is now opened, and water flows out from the smooth and rounded outlet. Determine the maximum water velocity (in m/s) at the outlet.

Jaymar bought a small water pump for his aquarium. The pump delivers 0.2 L/s at a net head of 2 m while connected to a small motor running at 1041 rpm. After a week the motor stopped working, so Jaymar bought a new motor which operates at half the speed of the original one. Predict the head (m) of the modified pump. Round off your final answer to 3 decimal places.
