8. The vapor pressure of water at 100°C is 101 kN/m², because water boils under these conditions. The vapor pressure of water decreases approximately linearly with decreasing temperature at a rate of 3.1 kNmC. Calculate the boiling temperature of water at an altitude of 3000 m, where the atmospheric pressure is 69 kN/m² absolute.

Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.
