Igcse Model Questions Vol1 2017 Physics Question 18
Practice objective / multiple choice question 18 from the 2017 Igcse Model Questions Vol1 Physics examination.
A U‑tube manometer has arms of equal cross‑section. The left arm is filled with mercury (density \(\rho_{Hg}=13,600\,\text{kg m}^{-3}\)). The right arm contains water (density \(\rho_{w}=1000\,\text{kg m}^{-3}\)) up to a height of \(0.30\,\text{m}\) above the mercury-water interface. The mercury levels differ by \(0.12\,\text{m}\) (the mercury in the left arm is lower). Calculate the pressure difference between the two ends of the manometer.
