Question

A piston-cylinder device contains 0.05 m3 of saturated water liquid at 300 kPa.

Determine the mass of the liquid inside the cylinder. ​

Answer 1

m = 50 kg

Step-by-step explanation:

The mass of the liquid water inside the cylinder can be given by the following formula:

`\rho = (m)/(V)\\\\m = \rho V`

where,

m = mass of the liquid water inside the cylinder = ?

V = Volume of the liquid water inside the cylinder = 0.05 m³

ρ = Density of the liquid water = 1000 kg/m³

Therefore,

`m = (1000\ kg/m^3)(0.05\ m^3)\\`

m = 50 kg
