To determine the volume of gas present at a pressure of 30 bar, we would need to know the temperature and the type of gas involved. The ideal gas law, PV = nRT, can be used to calculate the volume of gas present at a given pressure, temperature, and amount of gas. Without the temperature and the amount of gas (in moles), we cannot calculate the volume of gas present at 30 bar. **

Reducing the compressed air to 30 bar is generally cheaper than connecting the operating pressure to 8 bar. This is because reducing the pressure requires less energy and equipment compared to increasing the pressure. Additionally, operating at a lower pressure can also result in reduced wear and tear on equipment, leading to lower maintenance costs in the long run. Therefore, in most cases, it is more cost-effective to reduce the compressed air to 30 bar rather than connecting the operating pressure to 8 bar. **
