ICSE Class 10 Answered

The valve of a cylinder containing 12 KG of compressed gas is opened and the cylinder empties  in 1 minute 30 seconds if the gas comes out from the exit nozzle with an average velocity of 15 M per second find the force exerted on the cylinder

answered-by-expert Expert Answer
mass of the gas = 12 kg
mass flow rate coming out of the cylinder = 12 kg/ 90 s = 2/15 kg/s
 
force = mass flow rate × speed =( 2/15 kg/s )× ( 15 m/s )=  2 kg m/s2 = 2 N
