Numerical questions
A water tank has dimension of 6 mx 4 m X 4m find
the pressure given by the water tank at the botom
tom of the fank when it is half filled.​

Answer 1

Answer:

volume of the water tank = 5 * 3 * 2 = 30m^3.

At 4°C = 39.2°F water has its greatest density ( p ) of 1. Its weight = 30,000kg.

The Width and Length dimensions are not made clear in the specification.

It is therefore impossible to calculate the area upon which the weight rests and consequently determine the pressure = weight/area (N/m^2).

There are three possible answers based upon the height of the tank water.

Using: P = m * g * h

P(h = 5) = 30,000 * 9.8 * 5 = 147MN/m^2.

P(h = 3) = 30,000 * 9.8 * 3 = 882kN/m^2.

P(h = 2) = 30,000 * 9.8 * 2 = 588kN/m^2.
