Explanation:
The mixture of HFc-134a with high concentration of air at raised pressure can become combustible in presence of a ignition source, that is oxygen enriched environment.Thus at high pressure in a mobile air condition led to combustible of HFC-134a.
Answer:
The average speed of the oil is 1 m/s.
Explanation:
Given that,
Viscosity 
Radius r = 3.0 mm
Length = 1.0 m
Pressure = 200 kPa
We need to calculate the average speed of the oil
Using formula of pressure


Where, A = area
= density of oil
= viscosity
Put the value into the formula


Hence, The average speed of the oil is 1 m/s.
