coefficient

(b) Similarly obtain the phenol coefficient at 30 minutes contact period.

Of course you want to know how this coefficient has been found out, and how you can be sure it is correct.

I hope I have now kept my promise, and made it clear how the coefficient of centrifugal force may be found in this simple way.

How to find the coefficient, by which the amount of centrifugal force exerted in any case may be computed.

At high temperatures the resistance generally increases, but the temperature coefficient is irregular.
