Question
Tire gauges for air pressure, as well as most other gauges used in an industrial environment take into account the pressure due to the atmosphere of earth. That's why your car gauge reads 0 before you put it on your tire to check your pressure. That is called gauge pressure. The real pressure within a tire or other object contains pressurized stuff would be a combination of what the gauge reads as well at the atmospheric pressure. If a gauge on a tire reads 40.16 psi, what is the real pressure in the tire in pascals. The atmospheric pressure is 1.01x10^5 Pa.

- Blood pressure is measured when the blood is pumping (systolic) and when the heart is resting (diastolic). When pressure readings are given, the systolic is given first, and healthy blood pressure is around 120 over 80 mm Hg. Recall the density of mercury is 13.6 × 103 kg/m3. a. Suppose you have a blood pressure reading of 116 over 82 mm Hg. What is your systolic pressure, in newtons per meter squared? b. Suppose you have a blood pressure reading of 116 over 82 mm Hg.

- 1. The pressure gauge shown in Figure 1 consists of a spring inside vacuum chamber. The chamber is isolated from the a environment by a piston, which is free to move up or down. Ambient pressure exerts a force on the piston, which compresses the spring. The piston has a diameter of 30 mm. At sea level, where ambient pressure is 1 atm, the spring is compressed by distance xo = 14 mm relative to its relaxed length. Suppose the pressure gauge is lowered into water at a lake. At depth D, the spring is compressed by distance x, = 34 mm relative to its relaxed length. Calculate D. Show and explain your work.

The cylinder comes to rest some distance above the plunger. The plastic tube has an inner radius of 5.71 mm and is frictionless. Neither the plunger nor the metal cylinder allow any air to flow around them.
