A pressure head of 320 metres of water in meters of CCl4 (sp.gr = 1.6) will be__________________?
Correct answer: B. 200
- A. 100
- B. 200
- C. 320
- D. 160
Explanation
For the same pressure, pressure-head height varies inversely with specific gravity: h_CCl4 = 320/1.6 = 200 m. The denser CCl₄ column therefore needs less height than water.
