Unformatted text preview: derive an expression for the horizontal force F , per unit breadth, required to hold the gate in place. Check your result by showing that it gives zero when h 1 =h 2 and the hydrostatic result gh 1 2 2 when h 2 =0. HINT HINT 2 HINT 3 ANSWER (b) Also obtain expressions for the velocities V 1 and V 2 and the volume flow rate Q per unit breadth in the stream. Show that as h 2 approaches zero, V 2 approaches 2 gh 1 . Explain. HINT ANSWER...
