1. A system for determining an amount of back pressure a plug can hold in a pipe, the plug blocking a fluid flow or gas flow in the pipe in which a friction coefficient between the plug and the pipe is not known, the system comprising:
a means for determining the friction coefficient between the plug and the pipe;
a means for measuring a force in said means for determining the friction and for allowing the plug to be pulled through the pipe, said means for measuring the force comprising a dynamometer; and
a back pressure calculating program cooperative with said means for determining the friction coefficient and with the dynamometer in which values read by the dynamometer are entered so as to calculate a maximum back pressure value that the plug can hold according to the entered values.
