1) Water flows steadily along a horizontal pipe at a rate of `8 × 10^(-3)m^3`/s. If the area of cross – section of the pipe is `40 × 10^(-4) m^2`, Calculate the flow velocity of water.2) Find the total pressure in the pipe if the static pressure in the horizontal pipe is `3 × 10^4 Pa`. Density of water is `1000 Kg`/`m^3`.3. What is the net flow velocity if the total pressure is `3.6 × 10^4
