Chapter 15, Problem 15-130(choose chapter or problem)
15-130. The mini hovercraft is designed so that air is drawn in at a constant rale of 20 m3/s by the fan blade and channeled to provide a vertical thrust F. just sufficient to lift the hovercraft off the water, while the remaining air is channeled to produce a horizontal thrust T on the hovercraft. If the air is discharged horizontally at 200 m/s and vertically at 800 m/s, determine the thrust T produced. The hovercraft and its passenger have a total mass of 1.5 Mg. and the density of the air is pa = 1.20 kg/m3.
