City Guilds Model Questions Vol1 2023 Engineering Question 42
Practice objective / multiple choice question 42 from the 2023 City Guilds Model Questions Vol1 Engineering examination.
A water tank 15 m above the ground supplies water to a workstation through a straight steel pipe 200 m long and 0.10 m in diameter. The pipe's absolute roughness is \(\varepsilon =0.00015\) m. The required flow rate is \(Q=0.020\) m³ s⁻¹. Assuming turbulent flow of water (kinematic viscosity \(\nu =1.0\times10^{-6}\) m² s⁻¹) and using the Swamee‑Jain approximation \(f=0.25\big/\big[\log_{10}\big(\frac{\varepsilon}{3.7D}+\frac{5.74}{Re^{0.9}}\big)\big]^2\) for the Darcy‑Weisbach friction factor, calculate the total pump head (in metres) required to overcome both the static head and friction losses. Give your answer to one decimal place.
