Question
(a) Differentiate between hydraulic gradient line and total energy line. (6)
(b) A stationary curved plate deflects a $10 \text{ cm}$ diameter water jet through an angle of $120^\circ$ in the horizontal plane. Calculate the force required to hold the plate in position if the velocity of jet is $15 \text{ m/s}$. (7)
(c) A rectangular weir $0.75 \text{ m}$ high and $1.5 \text{ m}$ long is to be used for discharging water from a tank under a head of $0.5 \text{ m}$. Estimate the discharge (i) when it is used as a suppressed weir (ii) when it is used as a contracted weir. Take $C_d = 0.66$. (7)
