Question

Water flows in a horizontal tube as shown in figure. The pressure of water changes by 600 N/m2 between x and y where the areas of cross section are 3 cm2 and 1.5 cm2 respectively. Find the rate of flow of water through the tube.


 


  1. 189 cm3/s

  2. 199 cm3/s

  3. 169 cm3/s

  4. 179 cm3/s


Solution

The correct option is A

189 cm3/s


By equation of continuity

VyVx=3 cm21.5 cm2=2

By Bernoulli’s equation

Px+12ρv2x=Py+12ρv2y

PxPy=31ρv2x

vx=0.63 m/s

Q=Ax vx=(3 cm2)(0.63 m/s)=189 cm3/s
