Ing park ight, you tyres statisties from the dashboard and gotten the value as follows: Temperature of the air: 24°C Volume of air: 0.0165 m Absolute pressure of the tyre: 3.01 atm Current atmospheric pressure: 1.02 atm To confirm the value, you measure the pressure of the tyre with a gauge pressure and got the value of 1.99 atm. You then drive the car up to Genting Highland where the atmospheric pressure is 0.947 atm due to higher altitude. Once you have reached the destination, the temperature of the air in the tires has now risen to 42.0°C and the volume has risen to 0.0172 m. Assume ideal gas in the tyre, calculate the gauge pressure at Genting Highland. [CLO2-PLOe
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
