Question 1
Water at 20°C (density ρ = 1000 kg/m³) flows through a smooth horizontal pipe of internal diameter D = 0.1 m at a volumetric flow rate of Q = 0.0314 m³/s. What is the average fluid velocity in the pipe?
Correct Answer:
4.0 m/s
Question 2
A centrifugal pump transports liquid with a density of 1200 kg/m³ against a total dynamic head of H = 30 meters. Assuming local gravitational acceleration g = 9.81 m/s² and a pump hydraulic efficiency η = 75%, what is the electrical shaft power required for a volumetric flow rate Q = 0.05 m³/s?
Correct Answer:
23.5 kW
Question 3
For fluid flow in a circular pipe, at what threshold value of Reynolds Number (Re = ρ v D / μ) does the transition from stable laminar flow to turbulent flow typically commence in industrial piping design?
Correct Answer:
Re = 2,100
Question 4
According to the Darcy-Weisbach equation h_f = f × (L/D) × (v² / 2g), if the fluid velocity v in a pipe is doubled while keeping pipe diameter D, length L, and friction factor f constant, how does the head loss h_f change?
Correct Answer:
Head loss increases by a factor of 4 (4x)
Question 5
An ideal gas expands reversibly and isothermally at temperature T = 300 K from an initial volume V₁ = 1.0 m³ to a final volume V₂ = 2.0 m³. If n = 100 moles of gas are present and R = 8.314 J/(mol·K), what is the heat Q added to the gas during expansion?
Correct Answer:
172.9 kJ
