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))`

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.

Water flows steadily through a horizontal pipe of variable cross-section. If the pressure of water is P at a point where flow speed is v, the pressure at another point where the flow speed is 2v, is (Take density of water as rho ):

Water flows steadily through a horizontal pipe of variable cross-section. If the pressure of water is P at a point where flow speed is v, the pressure at another point where the flow speed is 2v, is (Take density of water as rho ):

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 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?
