The corss-sectional area of water pipe entering the basement is 4 x `10^(-4) m^(2)`. The pressure at this point is 3 x `10^(5) Nm^(-2)` and the speed of water is 2 `ms^(-1)`. This pipe tapers to a cross-sectional area of 2 x `10^(-4)m^(2)` when it reaches the second flooe.

The cross-sectional area of water pipe entering the basement is 4 cm^(-2) . The pressure at the point is 3.5 xx 10^(5) Nm^(-2) and the speed of water is 2.2 ms^(-1) . This pipe tapers to a cross-sectional area of 2 cm^(2) when it reaches the second floor 10 m above . Calculate the speed and pressure at the second floor. use g = 10 m//s^(2) .

A current of 4.8 A is flowing in a copper wire of cross-sectional area 3xx10^(-4) m^(2) . Find the current density in the wire.

Water flowing steadily through a horizontal pipe of non-unifrom cross-section. If the pressure of water is 4xx10^(4)N//m^(2) at a point where cross-section is 0.02 m^(2) and velocity of flow is 2 ms^(-1) . The pressure at a point where cross-section reduces to 0.01 m^(2) is 3.4xx10^(n) Pa. What is the value of n ?

At the mount of the tap area of cross-section is 2.0cm^(2) and the speed of water is 3m//s . The area of cross-section of the water column 80 cm below the tap is (use g=10m//s^(2))
