Variables Used

Total Force on Rocker Arm of Inlet Valve - (Measured in Newton) - Total Force on Rocker Arm of Inlet Valve is the total force acting onto the rocker arm of the inlet valve.
Mass of Valve - (Measured in Kilogram) - Mass of Valve is the mass (a measure of the amount of matter in valve) of the valve.
Acceleration of Valve - (Measured in Meter per Square Second) - Acceleration of Valve is the acceleration with which the valve opens or closes.
Maximum Suction Pressure - (Measured in Pascal) - Maximum Suction Pressure is the amount of pressure generated by the gases during its flow from an obstruction.
Diameter of Valve Head - (Measured in Meter) - Diameter of Valve Head is the diameter of the top part of valve of an IC engine, valve intakes and exhausts gases to and from an engine.

STEP 1: Convert Input(s) to Base Unit

Mass of Valve: 0.45 Kilogram --> 0.45 Kilogram No Conversion Required
Acceleration of Valve: 140 Meter per Square Second --> 140 Meter per Square Second No Conversion Required
Maximum Suction Pressure: 0.051 Newton per Square Millimeter --> 51000 Pascal (Check conversion here)
Diameter of Valve Head: 50 Millimeter --> 0.05 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_i = m*a_v+(pi*P_smax*d_v^2)/4 --> 0.45*140+(pi*51000*0.05^2)/4

Evaluating ... ...

P_i = 163.138265833175

STEP 3: Convert Result to Output's Unit

163.138265833175 Newton --> No Conversion Required

FINAL ANSWER

163.138265833175 ≈ 163.1383 Newton <-- Total Force on Rocker Arm of Inlet Valve

What is SI Engine?

A spark-ignition engine (SI engine) is an internal combustion engine, generally a petrol engine, where the combustion process of the air-fuel mixture is ignited by a spark from a spark plug. This is in contrast to compression-ignition engines, typically diesel engines, where the heat generated from compression together with the injection of fuel is enough to initiate the combustion process, without needing any external spark. Spark-ignition engines are commonly referred to as "gasoline engines" in North America, and "petrol engines" in Britain and the rest of the world. Spark-ignition engines can (and increasingly are) run on fuels other than petrol/gasoline, such as autogas (LPG), methanol, ethanol, bioethanol, compressed natural gas (CNG), hydrogen, and (in drag racing) nitromethane.
