thank you for educated

[@hks571]

good job

[@leckylouie]

Thank you! Cheers!

sir formula naman po please para sa mean effective pressure, kasi automatic calculation yung sa form eh. thanks

From the result of Banana Graph.
example: Area=3.6cm2
Area in mm2 = 3.6cm2 X 10mm/cm = 36 mm2
Length: 7.4cm
spring constant: 0.306Bar/mm (variable)
MEP = Area mm2 / (Length x spring constant)
example.
MEP = 36mm2 / ( 7.4cm x 0.306mm/bar)
MEP = 15.90 bars

@@leckylouie sir conflict po sa 3.6 cm2 = 360 mm2

[@leckylouie]

@@bimbimcool ung sa unit lang conflict sir pero ung value ng answer ganyan lumabas sir .times 10mm.thanx

@@leckylouie sir nakuha ko na icorrect natin sir.
Area of diagram = 3.6 cm2 = 360 mm2
Length of stroke = 74 mm
spring constant = 3.26 mm / bar
Mean indicated pressure = 360 mm2 / 74 mm X 3. 26 mm per bar
Pmean = 15.85 bars

joe de ta roy kumusta

ayos naman sir..
