SUMMARY
The discussion focuses on determining the minimum thickness required for exposed steel penstocks in hydro-electric dams, specifically addressing the challenges of calculating internal pressure increases due to water hammer. It is established that controlling the flow rate through slow adjustments mitigates the impact of water hammer. Additionally, matching the impedance of the penstock to the turbine minimizes energy reflection, while surge towers, although sometimes utilized, have minimal effect on water hammer dynamics.
