A liquid of mass 1.0 x 103kg fills a rectangular tank of length 2.5m and width 2.0m. If the tank is 4m high, what is the pressure at the middle of the tank?[g = 10ms-2]
A
1.0 x 104Nm-2
B
2.0 x 103Nm-2
C
1.5 x 103Nm-2
D
1.0 x 103Nm-2
Verified Correct Answer: D.
Physical Principles & Numerical Solution
Density of liquid = \(\frac{1 {\times} 10^3}{2.5 {\times} 2 {\times} 4}\)
= 50kgm3
pressure heg = 50 x 10 x \(\frac{4}{2}\)
= 1 x 103Nm-2
