kp: Unit Friction Slope

In dCraigJones/n185: Graphic functions for Fire-Flow Testing

Description

Unit Friction Slope

Usage

kp(D, C = 130)

Arguments

D	Pipe diameter in Inches
C	Hazen-Williams friction factor

Value

k' (numerical) unit friction slope for 1 LF of pipeline (corrected for PSI)

Examples

# friction factor for 5,000 LF of 12-inch pipe
k <- 5000*kp(12)

# Headloss at 2,000 GPM for 5,000 LF of 12-inch pipe
k*2000^1.85

#' # friction factor for 5,000 LF of 12-inch pipe at C=100
k <- 5000*kp(12, 100)

# Headloss at 2,000 GPM for 5,000 LF of 12-inch pipe
k*2000^1.85
