A horizontal nozzle of $30 \mathrm{~mm}$ diameter discharges a steady jet of water into the atmosphere at a rate of 15 litres per second. The diameter of inlet to the nozzle is $100 \mathrm{~mm}$. The jet impinges normal to a flat stationary plate held close to the nozzle end. Neglecting air friction and considering the density of water as $1000 \mathrm{~kg} / \mathrm{m}^{3},$ the force exerted by the jet (in $\mathrm{N}$ ) on the plate is

Next Question :
A venturimeter having a throat diameter of $0.1 \mathrm{~m}$ is used to estimate the flow rate of a horizontal pipe having a diameter of $0.2 \mathrm{~m}$. For an observed pressure difference of $2 \mathrm{~m}$ of water head and coefficient of discharge equal to unity, assuming that the energy losses are negligible, the flow rate (in $\mathrm{m}^{3} / \mathrm{s}$ ) through the pipe is approximately equal to
(A) 0.500
(B) 0.150
(C) 0.050
(D) 0.015
