Subtopic: Hydrostatic pressure and its measurement
Question Statement:
A spherical tank of 2 m diameter is filled with an edible oil of specific gravity 0.92. If the pressure measured at the highest point in the tank is 70 kPa, the total pressure (kPa) in the tank will be
Options:
(A) 80.5
(B) 85.3
(C) 88.1
(D) 92.2
Official Answer Key:
C
Step-by-Step Solution & Explanation
Maximum (bottom) pressure = pressure at top + γh = 70 + (0.92×9.81)×2 = 70 + 18.05 = 88.05 ≈ 88.1 kPa.
