Fluid Mechanics Viscosity Question 91
Question: An incompressible liquid flows through a horizontal tube as shown in the following fig. Then the velocity v of the fluid is
Options:
A)3.0 m/s
B)1.5 m/s
C)1.0 m/s
D)2.25 m/s
Show Answer
Answer:
Correct Answer: C
Solution:
If the liquid is incompressible then mass of liquid entering through left end, should be equal to mass of liquid coming out from the right end. $ \therefore \ M=m_{1}+m_{2} $ Þ$ Av_{1}=Av_{2}+1.5A,.,v $ Þ $ A\times 3=A\times 1.5+1.5A,.,v $ Þ $ v=1\ m/s $
