Hi, here we are given air volume inside the tank as 10 kg.
00:11
The tank's interior air pressure is equal to 350 kpa.
00:20
The temperature is equal to 27 degree celsius.
00:27
And the gas constant is equal to 0 .2870 kj per kgk.
00:39
Now, for the first part, the volume of the tank.
00:44
Now, let's assume that air is an ideal gas where pv is equal to mrt.
00:51
That is 350 into v is equal to 10 times 0 .2870 into 300 will give the value of v as 10 into 0 .2870 into 300 divided by 350 is equal to 2 .46 m3.
01:14
Now, moving towards the second part of the question, to find the value of heat transfer.
01:19
From first law of thermodynamics, q is equal to delta u plus w.
01:28
For a closed system, w is equal to p delta v.
01:32
Due to constant volume, delta v is equal to 0.
01:36
That is final volume and initial volume will be same...
