Part B
Determine the change in density of the oxygen A closed tank contains oxygen at 400" F and under an absolute pressure of 26 lb/in2 The temperature decreases to 300 F P2-P-0 slug/ ft3 Previous Answers Correct Part B Determine the change in pressure of the oxygen
When the atmospheric pressure is 1030 mbar , what is the absolute pressure (in Pa) in the tank if the height of the mercury in the open tube is 6.3 cm lower, than the mercury in the tube connected to the tank?
The ideal gas law states that PV = NkgT where P is the absolute pressure of a gas, V is the volume it occupies, N is the number of atoms and molecules in the gas, and T is its absolute temperature. The constant ko is called the Boltzmann constant and has the value kg = 1.38x10-23J/K. A very common expression of the ideal gas law uses the number of moles, n- N/NA (NA is Avogadro's number, NA=6.021023 per mole). PV...
What is the absolute pressure (in kPa) in the tank, Pa, if the manometer fluid is water (density 1000 kg/m'), H is 330 ft and Patm 101 kPa? Patm Po 0 Fluid
problem 40 with parts
40. The atmospheric pressure (force per unit area) on a surface at an altitude z is due to the weight of the column of air situated above the surface. Therefore, the difference in air pressure p between the top and bottom of a cylindrical volume element of height Az and cross-section area A equals the weight of the air enclosed (density ρ times volume V-: ΑΔε times gravity g), per unit area: Let Δ、→0 to derive...
what is the water's absolute pressure as it flows through this
construction? express answer in pascals
A golf course sprinkler system discharges water from a horizontal pipe at the rate of 7500 cm/s. At one point in the pipe, where the radius is 3.85 cm the water's absolute pressure is 2.45x105 Pa At a second point in the pipe, the water passes through a constriction where the radius is 2.15 cm
