Projected Width of Valve Seat given Diameter of Port and Diameter of Valve Head Solution

STEP 0: Pre-Calculation Summary

Formula Used

Projected Width of Valve Seat = (Diameter of Valve Head-Diameter of Port)/2
w = (d_v-d_p)/2
This formula uses 3 Variables

Variables Used

Projected Width of Valve Seat - (Measured in Meter) - Projected Width of Valve Seat is the projected width of the seat of the valve for a seat angle of 45 degrees and is perpendicular to valve length.
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.
Diameter of Port - (Measured in Meter) - Diameter of Port is the diameter of the opening of the port of an IC Engine.

STEP 1: Convert Input(s) to Base Unit

Diameter of Valve Head: 50 Millimeter --> 0.05 Meter (Check conversion here)
Diameter of Port: 40 Millimeter --> 0.04 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

w = (d_v-d_p)/2 --> (0.05-0.04)/2

Evaluating ... ...

w = 0.005

STEP 3: Convert Result to Output's Unit

0.005 Meter -->5 Millimeter (Check conversion here)

FINAL ANSWER

5 Millimeter <-- Projected Width of Valve Seat

(Calculation completed in 00.007 seconds)

What is a valve gear mechanism?

The valve gear mechanism is a subassembly of the IC engine and its function is to open and close the inlet and exhaust valves at a proper time with respect to the position of the piston and crankshaft. The fuel is admitted into the cylinder when the inlet valve is open. Also, the burnt gases escape when the exhaust valve is open. The main parts of a valve-gear mechanism are valve, spring, tappet, rocker arm, pushrod, cam, and camshaft.
