In a cylinder with a cross-sectional area A = 100 cm2 the air is at a Temperature t1 = 12C. The atmospheric pressure is equal to p1 = 101 kPa. At altitude h1 = 60 cm from the bottom of the cylinder there is an airtight, movable piston. By which distance will the piston sinks, when a weight of m = 100 kg falls on the piston and heats the air in the cylinder up to a temperature t2 =...

A mild steel plate that is 1.4 in. thick and cross section 2 ft. x 2 ft. is placed horizontally in the sun. The top surface of the plate is exposed to air at 90°F and the lower surface of the plate is exposed to air with a convective heat transfer coefficient of 3 Btu/h ftF. If the incident solar radiation on the plate is about 400 Btu/h, and the convective heat-transfer coefficient between the top surface and the surrounding...

An oil with a density of 340 lbm / ft3 and a viscosity of 15 cp is in a very large and atmospheric cylinder-shaped tank. The oil is 5 ft. High from the bottom. It will be pumped to the top of a tank at a rate of 30 gal / min with a system of 3 inches inside diameter and 75 ft. Length of steel pipe, 1 full open slide valve, 1 T connection and 4 90 ° bends....

cannot figure out 3-6
In units of A) N/m2 and B) Atmospheres, calculate the total pressure at the bottom of the Milwaukee Depth, the deepest part of the Bermuda Triangle, which reaches a depth of 8380 meters. 3. If the pressure in the hallway would suddenly drop by 10 %, and the room pressure remained at atmospheric pressure, what would be the amount of net force on the door, assuming the door has dimensions 3 ft x 7 ft and...

5-18E Hydrogen is contained in a piston-cylinder device at 14.7 psia and 15 ft'. At this state, a linear spring (F « x) with a spring constant of 15,000 lbf/ft is touching the piston but exerts no force on it. The cross-sectional area of the piston is 3 f?. Heat is transferred to the hydrogen, causing it to expand until its vol- ume doubles. Determine (a) the final pressure, (b) the total work done by the hydrogen, and (c) the...

The construction of a water pistol is shown in the figure below. The cylinder with cross-sectional area A1 is filled with water and when the piston is pushed (by pulling the trigger), water is forced out the tube with cross- sectional area A2. The radius of the cylinder and tube are, respectively, 1.50 cm and 1.30 mm, and the center of the tube is a height - 3,00 en above the center of the cylinder. (Assume atmospheric pressure is 1.013...
