A compressor receives 0.1 kg / s of R-134a at 150 kPa, − 0 ° C and delivers it at 1200 kPa, 50°C. The power input is measured to be 3 kW. The compressor has heat transfer to air at 100 kPa coming in at 20°C and leaving at 30°C. What is the mass-flow rate of air?

The mass flow rate of air through the compressor is = 1.044

Explanation:

Mass flow rate refrigerant = 0.1

= - 0 °c = 273 K

= 50 °c = 323 K

= 3 KW

= 20 °c = 293 K

= 30 °c = 303 K

From the continuity equation

= 0.1

Put all the values in above formula

0.1 × 1.5 × ( 273 - 323 )  + 3 = × 1.005 × ( 303 - 293 )

10.5 = × 10.05

= 1.044

Therefore the mass flow rate of air through the compressor is = 1.044

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about

answer:

the army does care about its soilders sir i think yout getting off on the wrong foot sir you need to respect our country were keeping the peole that want to d harm towards you out. so dont go saying we don't care cause we do
