A garden hose has inside cross-sectional are $4{ \mathrm{cm}}^2$ and opening in the nozzle at other end is $0.5{ \mathrm{cm}}^2$. The velocity of water in the segment of the hose which lies on the ground is $1 \mathrm{m}/\mathrm{s}$. If a man holds the nozzle at a height $1 \mathrm{m}$ from the ground, find

water pressure in the hose on the ground. Given pressure at the nozzle is $1.01 \times 10^{5}$ $\mathrm{Pa}$ and density of water is ${10}^3 \mathrm{kg}/{\mathrm{m}}^3$.
