mass flow rate of the fluid passing through the pipe.
Solution:
The mass flow rate ( ˙m) can be calculated using the formula:
˙m=ρ·A·v
where: ρ= 1,000 kg/m3(density of the fluid), A= 0.05 m2(cross-
sectional area of the pipe), and v= 2 m/s (velocity of the fluid).
Substitute the given values into the formula:
˙m= 1,000 kg/m3×0.05 m2×2m/s
˙m= 100 kg/s
Therefore, the mass flow rate of the fluid passing through the pipe
is 100 kg/s. “‘Sure, here is a numerical question on Fluid Dynamics
