Thanks for reply. Sorry for wrong info. The cut will be 30m water depth and total vertical pipe length is 1km. I used Orifice Discharging Freely into Atmosphere Q=CA x SQRT(2gh) but actually when it cuts, the air will come out of the pipe. It's not atmosphere. How to calculate? Area of Orifice...
HI! Could anyone help me? Water Depth is about 1km. the vertical pipe is also 1km length vertically and empty but we try to cut the bottom of pipe by blade so the water will flow inside the pipe from bottom. Do you know how to calculate the time to flood fully up to a sea level? Pipe size is ID...
Thank you for your ansewrs. But according to AISC construction manual table 7-1 Available shear strength of bolts. P.7-22, Why do only single and double shear are difined?
Bolts subject to shear are designed for both single and double shear. Double shear stress is half of single shear stress in case of same bolt. If double shear is better than single, why don't we use there triple shear, or quadruple shear, etc.? could you explain why triple share is not possible...
