At the beginning of the compression process of an air standard otto cycle. P1= 1 bar, T1= 290k and V1= 400cm^3. The max Temperature in the cycle is 2200 K and the compression ratio is 8.

Determine

A) the heat addition in KJ

B) the Net-work in kJ

c) the thermal efficiency

9. When administering CPR, what is breaths-to- compressions ratio?

1. 2 breaths every 30 compressions.

2. 1 breath every 30 compressions.

3. 1 breath every 15 compressions.

4. 2 breaths every 5 compressions
