Fluid Questions

A large containers (with open top) of negligible mass and uniform cross-sectional area A has a small hole of cross-sectional area a in its side wall near the bottom. The container contains a liquid density ρ and mass m₀. If the liquid starts flowing

The figure shows a liquid of given density flowing steadily in horizontal tube of varying cross – section. Cross sectional areas at A is 1.5 cm2 , and B 25 mm2 is , if the speed of liquid at B is 60 cm/s then (PA - PB) is: (Given PA and PB are liquid

Area of liquid film is 6×10 cm2 and surface tension is T = 20 dyne/cm, what is the work done to change area up to 12 × 10 cm2 :

The surface tension of water is 75 dyne/cm. The minimum vertical force is required to pull a thin wire ring of circumference 20 cm and weight 0.1 N. Find x.

An ideal liquid exhibits steady flow through a horizontal tube of varying cross-section. The widest and narrowest parts have diameters 7.5 cm and 3.0 cm respectively. Find the ratio of minimum velocity to maximum velocity.
