b. The head loss due to friction, h,, in a rising main is determined through the Darcy- Weisbach equation where f is the frictional constant is the effective length of the pipe, v is velocity, g is gravity and d is the pipe diameter. hy 4fbb² 2gd 2= -5 --5 30 +5 46--2-1f+2 V- There is consistently a ±2% error when determining the effective length of the pipe as well as fluctuations in the velocity readings generating variances in velocity of ±5% V What are the possible percentage variances in the calculated values of the head loss?
