Explain why in bernoulli theorem.
1. Why net work done is w1-w2 instead of this w1+w2. Because net means all.
2.why in this theorem kinetic energy increases.
3 why potential energy decreases.

Give the first answer.
Sorry forgot to answer it!! See basically you need to understand what is the concept behind it! When an incompressible fluid moves from a wide pipe to a narrower pipe it gains some kinetic energy , so as to maintain the volume flow. It follows conservation of energy which is the work done by it is equal to initial and final
i.e W*-W=0

You are almost right but,
See its very simple.... Just try to understand what I want to tell....
Net work done means W1 + W2 but
In this we need net work done on the fluid....
As We see W1 (work done by 1) is on fluid but W2 is not on fluid, instead opposite of W2 will be on the fluid and opposite of W2 is - W2,
So net work done is W1- W2
I hope this will help you
