A three-cylinder, two-stroke cycle SI automobile engine, operating at 3600 RPM, has peak cycle operating conditions of 2900°C and 9000 kPa. Cylinder temperature when the exhaust port opens is 1275°C.

Calculate:

(a) Cylinder pressure when the exhaust port opens. [kPa]

(b) Maximum flow velocity through the exhaust port. [m/sec]
