Model of a trompe powering a model of an airlift pump. Air pressure generated is about 6 inches water. (about 0.21 psi) or 1500 Pa. and it is used to pump water 32 inches high The power water was falling about13 inches (33cm) and the speed of the power water was 1.9 liters per minute. Watts from a water power source is M mass (kg per second) by 9.81 (Acceleration due to gravity) by height in meters. (a liter of water weighs one kg.) So 1.9 divided by 60 multiplied by 9.81 multiplied by 0.33 This gives the power of the water falling in the model. Result 0.1025 watts!
