Tire gauges for air pressure as well as most other gauges used in an industrial environment take into account the pressure due to atmosphere on earth that's why your car gauge reads zero before you put it in on your tire to check your pressure this is called gauge pressure. The real pressure with any tire or after or other objects containing pressurized stuff would be a combination of what the gauge reads as well as the atmospheric pressure. If a gauge on a tire reads 26.23 psi what is the real pressure in the tire pascals? The atmospheric pressure is 1.01×10 to the fifth power PA

c. volume d. density Answer: - Question 13 CLO5 The pressure of an ideal gas in a rigid vessel is 120 kPa and temperature is 50°C. If the pressure is increased to 160 kPa, what is the temperature of the gas inside the vessel.

The intake in the figure has cross-sectional area of 0.79 m² and water flow at 0.48 m/s. At the outlet, distance D = 180 m below the intake, the cross-sectional area is smaller than at the intake and the water flows out at 9.1 m/s. What is the pressure difference between inlet and outlet? MPa Reservoir Generator building Intake Outlet→

GAS LAWS A manometer contains a sample of nitrogen gas at a pressure of 15.4 psi. The level of mercury in the U-tube is 12.8 mm higher on the end open to the atmosphere. What is the atmospheric pressure in psi?

Name Chapter 20 Gases Boyle's Law A movable piston encloses 0.78 m³ of gas in a cylinder. The piston is then pushed downward, changing the volume of the gas to 0.36 m³ and the pressure to 2.8 kPa. What was the original pressure of the gas? 1. Read and Understand What information are you given? initial volume of the piston = V₁ = 0.78 m³ final volume of the piston = V₂ = 0.36 m³ final pressure of the piston = P2 = 2.8 kPa 2. Plan and Solve What unknown are you trying to calculate? original pressure of the piston = P₁ What mathematical equation can you use to calculate the unknown? Boyle's law: P₁V₁= P₂V₂ Rearrange the equation to solve for the unknown variable. P₂V₂ P₁₂₁= Substitute the values you know into the equation.
