leaving a vehicle in an indoor car park for a night, you check the tyres’ statistics from the dashboard and gotten the value as follows: Temperature of the air: 24°C Volume of air: 0.0165 m^3 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^3. Assume ideal gas in the tyre, calculate the gauge pressure at Genting Highland.
Viscosity
The measure of the resistance of a fluid to flow is known as viscosity. Most fluids have some resistance to motion, the resistance provided by the fluid is called viscosity. This resistance is created by the force of attraction between the fluid molecules. If you pour water through a funnel, it flows easily and quickly, because it has very little resistance. But if you pour honey through a funnel, it may take a little time longer, as the density of honey is high.
Poiseuille's Law
The law of Poiseuille or Poiseuille's equation states that the pressure drop of an incompressible fluid especially a liquid in a laminar flow that passes through a cylindrical tube of length L, radius r, pressure gradient ΔP, and mainly depends on the viscosity of the fluid is nothing but the pressure difference of the layers of fluids. ΔP=P1-P2
Drag Forces
Forces that occur due to the movement of fluid are known as fluid mechanics. Following are the fluids present:
