Pump Pressure & Flow Calculator
This page has two online calculators.  One is used to calculate the required pump pressure needed to generate a specified nozzle pressure.  The other calculates the maximum amount of flow through a hose under the given operating conditions.

Tanker Shuttle Calculator
 This online calculator generates a report showing how much water is available one a fire scene on a minute-by-minute basis for the first two hours of a response.  The inputs are the  number, size, and cycle time of the tankers involved in the shuttle operation, as well as the initial response apparatus.

Tanker Shuttle Calculator – ISO Version
Very similar to the calculator above, but with some modifications to adapt it to the ISO 2-hour Water Deliver Test method.  This version allows you to specify an initial water flow (usually 250 gpm) that starts 5 minutes after arrival on scene, along with an improved water flow that starts 15 minutes after arrival on scene.
