FLUIDS DOUBT

BITSAT 2015 Guidance › Mechanics questions › FLUIDS DOUBT

PLEASE EXPLAIN TO ME THE STEPS THAT I'M SHOWING HERE :

This is a popular Irodov problem. (FLUID IS FILLED UPTO THE BRIM ). I am putting down a few lines of what i can't understand here ..... if you have good will....please do help me :

1) h = h₂ - h₁
where h is the head loss causing liquid flow. MEANING ???

2) Cross sectional area of the tube decreases from S to s. So, the force on water is (P-p)s where P = pressure energy at the top and p = pressure at mouth of area s.

3) Horizontal force tending to pull the tube out of the tank = Ïgh x S where Ï is the density of the liquid. Now what the hell is this ???

1) h is the potential head per unit weight {mgh/mg = h}
