Chapter 1 – Problem 1.13
1.13 Consider a thin-walled pipeline system with a reservoir at one end and a valve at the other end discharging to atmosphere under steady state conditions.
Closing the valve instantaneously generates unsteady flow conditions. Select all applicable answers listed below.
i. Flow in the pipeline close to the valve drops and a positive pressure wave is generated that travels towards the reservoir.
ii. Flow in the pipeline close to the valve drops and a negative pressure wave is generated that travels towards the reservoir.
iii. Flow in the pipeline close to the valve increases and a positive pressure wave is generated that travels towards the reservoir.
iv. Flow in the pipeline close to the valve increases and a negative pressure wave is generated that travels towards the reservoir.
v. None of the above.
