## Study Notes

### Pump Chart Introduction

• The Pump Chart is a tool used by Engineers to calculate pump pressures and flows
• It is essential to review the Pump Chart periodically to maintain proficiency in pump operations

### Pump Discharge Pressure (PDP) Formula

• The PDP formula is used to calculate the total pressure required to pump water through a hose
• The formula takes into account nozzle pressure (NP), friction loss (FL), elevation (ELEV), and appliance pressure (APPL)

### Friction Loss (FL) Calculation

• Friction loss is calculated using the hose diameter and the flow rate of the nozzle
• The friction loss is then multiplied by the length of the hose (in hundreds of feet)

### Elevation (ELEV) Calculation

• Elevation is calculated based on the number of floors above or below the pump
• The elevation loss or gain is then added or subtracted from the total PDP

### Appliance Pressure (APPL)

• Appliance pressure is the pressure required to operate a specific appliance, such as a deck gun or aerial waterway
• The appliance pressure is added to the total PDP

### Nozzle Pressure (NP)

• Nozzle pressure is the pressure required to produce a specific flow rate from a nozzle
• The nozzle pressure is affected by the nozzle size and the flow rate

### Crosslay and Extended Hose Operations

• Crosslay operations involve using multiple hoses to increase flow rates
• Extended hose operations involve using longer hoses to reach remote areas
• The Pump Chart can be used to calculate the PDP for both crosslay and extended hose operations

### Trash Line Operations

• The trash line consist of 100’ of 1.75” hose with an Elkhart Chief nozzle that delivers 175 GPM
• The trash line is used for overhaul and vehicle fires
• The Chief Nozzle will NOT be used for structural firefighting

### Denver Bundles and High-Rise Operations

• Denver Bundles consist of 150’ of 2.25” hose with a 1” tip that delivers 210 GPM
• High-Rise Operations involve using longer hoses to reach higher floors
• The Pump Chart can be used to calculate the PDP for high-rise operations

### Examples of Pump Chart Calculations

• Multiple examples of pump chart calculations are provided, including single crosslay, two crosslays, 1.78” extended from 2.5” bulk bed, Blitz Line, and Trash Line operations
• Each example includes the calculation of nozzle pressure, friction loss, elevation, appliance pressure, and pump discharge pressure.
