Question 1.
What is the formula for calculating static head?
Show hintHide hint
Consider the vertical heights involved.
Question 2.
how do you calculate fluid velocity in a pipe?
Show hintHide hint
Remember to convert flow rate to cubic meters.
3Question 3.
What is the formula used to calculate the head loss in pipes?
- hf = f(L/D)(V²/2g)
- hf = P/(ρg)
- hf = V²/(2g)
Show hintHide hint
Think friction and pipe characteristics.
4Question 4.
True or False: Minor losses are not significant when calculating total head loss.
- True
- False
Show hintHide hint
Consider all factors affecting flow.
Question 5.
A pump needs to lift water 30m against a static head. With a flow rate of 0.05 m³/s and total losses of 5.5m, estimate the power required.
Show hintHide hint
Break the calculations down for clarity.
Question 6.
Given a pipe of diameter 10cm, find the velocity if it's discharging 0.01 m³/s. Then calculate the major loss across 100m of this pipe with a friction factor of 0.02.
Show hintHide hint
Calculate area and velocity first, then apply equations accordingly.
