Refrigerant entering the compressor of a refrigeration system is sub-cooled liquid
The liquid refrigerant is sub-cooled to ensure that only liquid and not the vapour enters the throttling valve. In a refrigeration system, the superheating decreases COP increase refrigerating effect but increasing amount of work done. The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs.

#SPJ4
Answer:
volume is 0.1 L
Explanation:
you can use the equation density=mass/volume
100 = 1000 / v
divide by 1000 on both sides
0.1 = v
Answer:
114.075 N
798.525 Nm
Explanation:
C = Drag coefficient = 0.5
ρ = Density of air = 1.2 kg/m³
A = Surface area = 9 m²
v = Velocity of wind = 6.5 m/s
r = Height of the tree = 7 m
Drag equation
Magnitude of the drag force of the wind on the canopy is 114.075 N
Toque is given by the product of force and radius
Torque exerted on the tree, measured about the point where the trunk meets the ground is 798.525 Nm
No it isn't.
Gravity does work on the tile, causing its momentum
and its kinetic energy to increase.
Answer:Surface wave
Explanation:
Longitudinal wave is perpendicular to the wave motion and transverse wave is the same as the wave motion
