Resistive index, or RI = [(Peak systolic velocity) - (Lowest diastolic velocity)]/(Peak systolic velocity)
What is the formula for purchasing managers index?
formula for writing index
to calculate viscosity index
Viscosity is resistance to flow of oil Viscosity Index is a scale to measure viscosity
Insulation resistance test: This test is used to find the insulation resistance of motor for 1 min or 10 min through high voltage insulation tester. By this we can find the insulation level. Polarization index: This is the ratio between insulation resistance for 10 min to insulation resistance for 1 min.
Umm... E=MC²
diesel index = aniline point *API(1/100)
Polarization Index is an indicator which gives an idea of the cleanliness of the windings. It is a ratio of the Insulation Resistance Measured for 10 minutes to the insulation resistance value measured after 1 minute. Since it is a ratio; it does not have any units.Polarization Ratio = Insulation Resistance after 10 minutes/ Insulation Resistance after 1 minuteThe Polarization Index should be above 2.0 to be permissible. Machines having PI below 2.0 cannot be operated. The Polarization Index does not have any significant relation with temperature upto 50 deg. C. However, the Polarization Index test should not be conducted at a temperature beyond 50 deg. C

how can we calculate cpi(consumer price index) .
A low resistance ohmmeter is used
