ohn’s automobile has a three-liter SI-V6 engine that operates on a four-stroke cycle at 3600 RPM. The compression ratio is 9.5, the length of connecting rods is 16.6 cm, and the engine is square (B=S). at this speed, combustion ends at 20o  at T.D.C. This engine is connected to Dynamometer which gives a brake output torque reading of 205 N-m. At his speed, air enters the cylinders at 85 kPa and 60o C, and the mechanical efficiency of the engine is 85%. Calculate: (a) Brake power, HP || (b) Indicated Power, HP || (c) Brake Mean Effective Pressure,

Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.
