Question

an ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27c and 750 kj/kg of heat is transferred to air during the constant volume heat addition process. determine the pressure and temperature at the end of the heat addition process

Answer 1

The pressure and temperature at the end of the heat addition process are 494.96 kPa and 1539 K respectively.

What is pressure?

The force that is applied over a given area is measured as pressure. The units of pressure are frequently Pascals (Pa), newtons per square meter (N/m2 or kg/ms2), or pounds per square inch (Psi). There are additional units as well, such as the atmosphere (atm), torr, bar, and meters sea water (msw).

Either the capital P or the lowercase p is used to represent pressure in equations.

An equation's units are used to express pressure, which is typically expressed as follows:

P = F / A

where P is pressure, F is force, and A is area.

A scalar quantity, pressure, exists. which means it has a magnitude but no direction. Given that the force usually has a clear direction, this may seem confusing. The pressure of a gas inside a balloon may be helpful to keep in mind.
