The blood pressure in the upper arm of a healthy person is 120 mmHg. Find out how much (h) the blood will rise in the tube if a vertical tube with its end open to the atmosphere is connected to the veins on that person's arm. The density of mercury is 13600 kg / m3 and the density of blood is 1050 kg / m3. Take the gravitational acceleration as 10 m / s2.

A manometer containing two oils is used to assess the pressure of air in a storage tank.  Given the configuration of the oils in the picture, calculate the pressure in the tank.  The density of air is negligible to the density of the oils (?oil1 = 1000 ??/m3; ?oil2 = 400 ??/m3 ). The height of oil 1 is 1 ?, and the height of oil 2 is 0.8 ?.  The atmospheric pressure is 98 ???. The manometer is ipen to the atmosphere.

Consider a tall building. The air pressure at the bottom of the building is 101155Pa. The top of the building is 363m above. Assuming that the air density is constant at 1.225kg/m³, what is the percentage drop in pressure at the top of the building relative to the pressure at the bottom? Give your answer to 1 decimal place. Use the acceleration due to gravity of 9.81m/s².

An aquarium 7ft long, 3ft wide, and 5ft deep is full of water. The gravitational acceleration is g = 32ft/s². The density of water is p = 1.95slug/ft³. Answer the following questions. 1. Find the hydrostatic pressure on the bottom of the aquarium. Answer (in pounds per sq. foot): 2. Find the hydrostatic force on the bottom of the aquarium. Answer (in pounds): 3. Find the hydrostatic force on one end of the aquarium. Answer (in pounds): FI

Water is ejected vertically from a pressurized tank as shown in Figure 2. The "3 atm" pressure value is an absolute pressure value.      Figure 2 Calculate the gauge pressure at the bottom of the tank in kPa if the height in the tank is H = 4.1 m. Assume the density of water is 1000 kg/m3 and 1 atm = 1.01 x 105 Pa. Use g = 9.81 m/s2.

if atp pressure is 101 kpa, and total pressure of a gas is 428 kPa, its gauge pressure is

For the manometer shown in the image, all fluids are at 20°C. If PB- PA = 90 kPa, determine the height H in centimeters. The specific weight of water is 9790 N/m³ and the specific weight of mercury is 133100 N/m³. Meriam red oil, SG = 0.827 Water 18 cm H 35 cm Numeric Response B Mercury

A bicycle tire pump has a piston with area 0.44 inches squared. If a person exerts a force of 30 lb on the piston while inflating the tire, what pressure does this produce on the air in the pump? Give your answer in psi.

A glass jar weighs 30 g. The jar weighs 80 g when filled with water and it weighs 105 g when filled with syrup. Calculate the specific gravity of the viscous liquid.

A vat contains a mixture of oil and water. The water forms a lower layer which is 0.8 m deep, and above it there is an oil layer 0.3 m thick. The density of water is 1000 kg/m³, and the density of oil is 800 kg/m³. Find the force on a flat door at the bottom of the vessel that has a cross-sectional area of 0.5 m². The acceleration due to gravity is 9.81 m/s². Oil, P. = 800 kg/m³ h, = 0.3 m %D Water, pw= 1000 kg/m3 h, = 0.8 m A = 0.5 m² O a. 5.1 kN O b. 5.4 kN Ос. 1.28 kN O d. 4.32 kN е. 10.2 kN
