Help needed for this question -- Air pressure in a bike tire
The Pressure gauge on a bike pump reads 8 bar at sea level on a day when the temperature is 21°C. Assume that the gas constant for air is 286.9 J/Kg K
a) What is the density of the air in the tyre?
b) What is the weight of the air in the tyre, if the diameter of the wheel is 0.66m and the diameter of the inner tube is 4cm
Help would be greatly appreciated
also in SI units please :)
pv=mRT
p= 8bar
R= 286.9
T= 273+21 294
m=?
equation V=mRT/P?
