What is the formula for calculating the flow rate (Q) of a liquid with a density (ρ) of 1000 kg/m3, a pipe diameter (of 0.3 meters, and a velocity (of 2 m/s?
A. Q = π * (D/2)^2 * v
B. Q = ρ * π * (D/2)^2 * v
C. Q = ρ * π * D^2 * v / 4
D. Q = π * D^2 * v / 4
Answer:C
What is the formula for calculating the flow rate (Q) of a liquid with a density (ρ) of 1000 kg/m3, a pipe diameter (of 0.3 meters, and a velocity (of 2 m/s?
A. Q = π * (D/2)^2 * v B. Q = ρ * π * (D/2)^2 * v C. Q = ρ * π * D^2 * v / 4 D. Q = π * D^2 * v / 4
Explanation: The flow rate (Q) of a liquid with a density (ρ) of 1000 kg/m3, a pipe diameter (D) of 0.3 meters, and a velocity (v) of 2 m/s can be calculated using the formula Q = ρ * π * D^2 * v / 4, where D is the pipe diameter in meters, v is the fluid velocity in m/s, and ρ is the fluid density in kg/m3.
