A cube-shaped water tank having 6 ft side lengths is being filled with water. The bottom is solid metal but the sides of the tan
Mekhanik [1.2K]

Answer:

0.033 ft

Step-by-step explanation:

Let g = 32.2 ft/s2 and h be the maximum height that water can be filled before the sides shatter.

Pressure is distributed from 0 to maximum at the bottom like the following equation:

P = \rho gh

So the force generated by water pressure on the side of the tank is

F = PA = \rho ghs/2

where s = 6ft is the side length of the tank. This force cannot be larger than 200lb

\rho ghs/2 \leq 200

62.4*32.2*h*6/2 \leq 200

h \leq 0.033 ft

For a fixed amount of gas at a constant temperature, the volume of the gas is inversely proportional to its pressure. The functi
malfutka [58]
The relation between pressure and volume is given as
v = 18000/p
where
v = volume, in³
p = pressure, lb/in²

When the pressure is p = 900 lb/in², then the volume is
v = 18000/900 = 20 in³

Answer: 20 in³
