In a horizontal pipeline of uniform cross section the pressure falls by `8 N//m^(2)` between two points separated by `1 km`. If oil of density `800 kg//m^(3)` flows through the pipe, find the change in `KE` per kg of oil at these points.

In a horizontal pipe line of uniform cross-section, pressure falls by 5 Pa between two points separated by 1 km. The change in the kinetic energy per kg of the oil flowing at these points is (density of oil =800kgm^(-3))

Water is flowing steadily through a horizontal pipe of non-uniform cross-section. If the pressure of water is 4 xx 10^4 N//m^2 at a point where cross-section is 0.02 m^2 and velocity of flow is 2 m//s . What is the pressure at a point where cross-section reduces to 0.01 m^2 ? .

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 ?

In a horizontal oil pipeline of constant cross-sectional area the pressure decrease between two point 300 km apart is 5000 pascal (1 pascal = 1 newton per square meter). What is the loss of energy per unit volume per unit distance? [Hint : Loss in energy =(P_(1))/(rho)-(P_(2))/(rho) because (P)/(rho) is pressure energy per unit mass and loss in energy per unti volume =P_(1)-P_(2) .]

Water is flowing steadily through a horizontal tube a of non uniform cross-section. If the pressure of water is 4xx10^(4)N//m^(2) at a point where cross-section is 0.02m^(2) and velocity of flow is 2m//s , what is pressure at a point where cross-section reduces to 0.01m^(2)

The figure shown a pipe of uniform cross-section inclined in a vertical plane. A U-tube manometer is connected between the point A and B. If the liquid of density rho_(0) flows with velocity v_(0) in the pipe. Then the reading h of the manometer is

There is a conical pipe of radii of its two ends as 0.2m and 0.02m with 20 N//m^(2) as the pressure difference along its length. A liquid of density 1.00 xx 10^(3) "kg/m"^(3) is flowing through the pipe. Calculate the rate of flow of liquid through the pipe.

Water flows steadily through a horizontal pipe of a variable cross-section. If the pressure of water is p at a point where the velocity of flow is v, what is the pressure at another point where the velocity of flow is 2v, rho being the density of water?
