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
Correct Answer: Option D
Explanation
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
