1-What pressure difference (in kPa) must be generated across the length of a 20 cm vertical drinking straw in
order to drink a water like liquid of density 1.0 gm m–3. (g = 10 m/s2
2= A gas cylinder of 5 lit. capacity contains air under a pressure of 20 atm at 300 K. The air is to inflate cycle tubes
to a capacity of 3.5 lit. under a pressure of 4 atm. How many tubes can be inflated at the same temperature
