Understanding the Capacities of the Mark 3 Pump - Digital-Flipbook
This 32 page digital book is the exact same as the print version and covers basic hydraulics instruction as it pertains to portable pumps in a far more understandable manner to the new comer than any other course you will likely take under the NWCG.
Covers Head Pressure, Friction Loss and Nozzle Pressure.
The book explains why and demonstrates why it takes .434 psi to raise water one foot and further the book explains how we deterime such and what the differense between rule of thumb and actual numbers.
The book covers rounding numbers errors why you should avoid such.
The book covers friction loss, and Nozzle pressure and explains how and where nozzle pressure comes from.
Provides instruction on how to read the Mark III pump curve and further teaches you how to understand and interpret the pump curve so if you have a hoselay that goes on for a couple miles, you can easily determine how many pumps you need to obtain. (Under NWCG, instruction on how to read pump curves is non existent). The lack of instruction on pump curves and their meaning is due to the fact that not a single course covers it, yet it is the most valuable tool you can have to understand what your pump is capable of.
Covers Dangers of Hydraulics and also includes a section on how to determine the temperature rise in degrees per minute if deadheading were to take place.
At the back of the book are the most common hydraulics conversion factors.
