Anear-surface parcel of moist air is at a pressure of 870 mb (where 100 mb = 1 pa), with a temperature of 12℃ and a relative humidity of 95%. a) what is the saturated vapor pressure (in pa) of the air? explain the physical meaning of saturated vapor pressure. how does it change, if at all, as the temperature increases? how does it change, if at all, as the humidity level (i. e. concentration of water vapor molecules) of air changes?

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
