Thank you! You really saved me!I was stuck while doing my assignment and you came to the rescue
I'm probably going to tell people about this channel, more content will be appreciated

Please help in finding out the upstream and downstream depth of the channel. Which is given as width 30m and water depth 1m

[@fareshanna6861]

thank you a lot

Any chance you could have a look at a similar question for me to see if you’re able to solve it?

[@hensterfrianlegara3525]

To find the y easily you can put the equation on calculator ang use shift solve.

[@fluidsexplained1901]

Yep, this is true! But this is the way to do it the old-fashioned way if you don't have a cleaver calculator!

[@Fredykingsabu1998]

can you solve it without using trial n error by solving for y0?

[@fluidsexplained1901]

Yes, but it is a whole load of rearranging and algebra! I think for engineers this is the simplest solution.
