How a deadweight tester can measure extremely high pressures (up to 10,000 psi in some applications).
Concept:
A deadweight tester is a type of piston cylinder used to measure the device. It is most exact instruments for the electronic or mechanical calibration to measuring the instruments.

- Perfect vacuum refers to a region that is completely devoid of particles. Pressure in perfect vacuum would be zero. On Earth, achieving a perfect vacuum is quite difficult in practice. In a modern physics laboratory with state-of-the-art vacuum systems, one may achieve a pressure of 1 nPa (1 × 10-9 Pa). This is referred to as ultra-high vacuum. Suppose you have a vessel of volume 1 m³ filled with air at a temperature of 300 K (approximately room temperature). Suppose a vacuum system is used to pump air out of the vessel, reducing the pressure from an initial value of 101325 Pa (1 atm) to a final value of 1 nPA. Assume that the volume and temperature remain constant. Calculate the initial and final numbers of molecules in the vessel at atmospheric pressure and at ultra- high vacuum (1 nPa). Comment: Perhaps surprisingly, even at ultra-high vacuum there is still a large number of particles in the vessel: 0 « N; « N;.A viewing window on the side of a large tank at a public aquarium measures 50 in. by 60 in.

- A high-altitude balloon is partially filled with 3 m3 of helium at sea level. As the balloon ascends through the atmosphere, the pressure drops and the gas expands. When it reaches its maximum volume of 7 m3, what is the pressure? (Assume the temperature does not change.)Integrated circuits are manufactured in vacuum chambers in which the air pressure is 1.00x10-10 mm of Hg.You have a tube where water enters at a velocity of 10.0 m/s, ascends 5.0 m, and then exits. The pressure pushes the water in at 250 kPa, and is measured come out at 150 kPa. The outcoming water is, faster than the incoming water. slower than the incoming water. the same speed as the incoming water.
