Vacuum (zero pressure) 2) A pipe narrows until its diameter is 70% of its original size and the water now flows at 1.4ms. What is the pressure difference between the wide and narrow ends of the pipe? (Treat as an Ideal Fluid) 3) Be sure to draw Free Body diagrams and apply Newton's 2nd Law to determine the tension in the strings below? ter75 cm3 of 100 cm3 of aluminum, density plastic, density Pr = 840 kg/m 3

Explanation / Answer

1) as we go up the fluid, pressure decreases with height,

Relation is as follow,

delta(P) = rho g h

P1 - P_vaccuum = rho g h

(0.65 x 101325 Pa) - 0 = (1000 x 9.8 x h)

h = (0.65 x 101325) / (1000 x 9.8)

h = 6.72 m .......Ans
