Consider air entering an ADIABATIC chamber at a rate of 100 lbm/s at 1 atm and 70°F (note non-absolute temperature scale). The air leaves this chamber at 20 atm. Suppose that the kinetic energy in the flow stream is negligible (i. e. u1 ≈ u2 ≈ 0). Determine: (a) exit temperature T2 and specify whether this is a minimum or a maximum temperature value and (b) amount of horsepower associated with this process and specify whether it is input or output.

Which expression allows you to determine the mechanical advantage of an inclined plane? a. height of plane / input force b. length of plane / input force c. length of plane / height of plane d. height of plane / length of plane

Samir watches a 100-minute movie on his spaceship. maria's spaceshipe flies in the same direction as samir's spaceship but she observes his move to last 125 minutes and his spaceship to be 40 m long. how long does samir observe his own spaceship to be? according to an observer on earth, planet x is stationary. maria and samir depart earth on their spaceships at the same time, each flying at 0.5c. maria flies toward planet x and samir flies in the opposite direction. according to maria, her voyage to planet x takes 9 years. how many years does marias voyage take according to samir?
