# Quantity of watersheds (homework)

• _medo88_

#### _medo88_

I'm new on this forum, so I hope I picked the right thread.

For my Physics, I heve to do a homework.

Because the height of tide at entry of Mediterranean to Adriatic sea is negligible, assess from this and geographic data, how much amount of water sheds from Mediterranean to Adriatic sea.

height of tide in Tržaški zaliv=60cm

I'm apologising myself for mistakes I made in text.

TNX

Welcome to PF!

Hi medo88! Welcome to PF!

First, you need to find the area of the Adriatic sea.

Then draw a diagram for yourself … show the surface of the water at low tide and at high tide (or does the question only want half of this?) … what shape do you think that surface should be?

Yes, I was thinking that if this is a shape of triangle?? But, I'm not shure if that is right.

It's probably much more complicated than a triangle …

but I think that is what the homework wants you to use.

So what is the volume?

Ok, tnx.
I just asked, because I wasn't sure, it looked to easy.

I calculated and the result was 37 Tl , what do you think??

I've no idea … you have to show me your calculations!

l...length=783,3 km
w...width=157.4 km
t...difference between low and high tide=60 cm

(l*w*t)/2=37Tl

Yes that looks like the right formula!

hmm … I agree with the 37, but not the Tl.

How do you get that?
