A box-shaped metal can has dimensions 18 in. by 3 in. by 8 in. high. All of the air inside the can is removed with a vacuum pump. Assuming normal atmospheric pressure outside the can, find the total force (in lb) on one of the 3-by-8 in. sides. (Enter the magnitude.)
A mercury filled manometer with two unequal length arms of the same cross-sectional area is sealed off with the same pressure Po in the two arms (see figure below). With the temperature constant, an additional 10 cm³ of mercury is admitted through the valve at the bottom. The level on the left increases by 6 cm and the level on the right increases by 4 cm. Find the pressure Po. 50 cm Po WH Ø 30 cm
A- Given that the volumetric flow rate for a fluid within a circular cross-section tube can be represented by Q= πΡΑ ΔΡ 8μL where r is the tube radius, µ is the fluid viscosity, P is the pressure drop across the tube, and L is the tube length, calculate the pressure drop across a tube of length 1 m and diameter of 23 mm. The fluid is blood (μ = 0.0035 N.s/m²) and has a volumetric flow rate of 4.5 L/min. Assuming the same conditions, what would the required pressure drop be for water (μ = 0.001 N.s/m²) and chocolate syrup (μ = 150 N.s/m²).
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 the Earth. That's why your car gauge reads 0 before you put it on your tire to check your pressure. This is called gauge pressure. The real pressure within a tire or other object containing pressurized stuff would be a combination of what the gauge reads as well at the atmospheric pressure. If a gauge on a tire reads 13.55 psi, what is the real pressure in the tire in pascals? The atmospheric pressure is 1.01x105 Pa.
