Given the barometric pressure of 14.7 psia (29.92 in Hg abs) make these conversions: a.) 90 psig to psia and to atmosphere, b.) 15 in Hg vacuum to in. Hg abs and to psia, c.) 20 psia to psi vacuum, and to Pa, d.) 15 in Hg gage to psia, to torrs, and to Pa. ( 1 atmosphere = 760 torrs) *

The height of a cylindrical tank, containing 20 lb of gas at 70 psia and 115 Farenheit, IS TRIPLE ITS DIAMETER; the gas constant is R = 45 ft lbf/lbm R. find.

Calculation of the instantaneous velocity at a specific time,given x is in meters and t is in seconds.

In an isentropic process, the volume of 500g of an ideal gas (cp = 0.52kJ/kg-K, cv= 0.32kJ/kg-K) was increased from 20L to 100L. If the initial pressure of the gas was 760kPa, compute for the final temperature in oK.

The centrifugal air compressor of a gas turbine receives air

from the ambient atmosphere where the pressure is 1 bar and

the temperature is 300K. At the discharge of the compressor,

the pressure is 4 bar and the temperature is 480K and the

velocity is 100 m/s. The mass flow rate of air is 15kg/s. (a)

Determine the power required to drive the compressor and

(b) Explain why the given air exit temperature is more or less

than the reversible adiabatic compression temperature.
