Q

Another method of evaluating water tender performance involves using a series of formulas originally developed by the __________ (ISO)

Rating Bureau

123
Q

The first ISO formula assumes an average travel speed between dump and fill sites at _____mph. If road condition allow faster or sloower speeds it must be adjusted.

you have to double the miles for round trip

A
125
Q

Handling time = Fill Site Time + Dump Site Time

Travel Time= 0.65 + (1.7)(distance)

Flow = 0.9 x TS divided by Travel time + Handling time

A
126
Q
