The pressure in a section of horizontal pipe with a diameter of 2.5 cm is 139 kpa. water ï¬ows through the pipe at 2.9 l/s. if the pressure at a certain point is to be reduced to 101 kpa by constricting a section of the pipe, what should be the diameter of the constricted section? the acceleration of gravity is 9.81 m/s2 . assume laminar nonviscous ï¬ow.

d = 2*0.87 = 1.75 cm

Explanation:

by using flow rate equation to determine the  speed in larger pipe

= 591.10 cm/s

 = 5.91 m/s

by Bernoulli's EQUATION

solving for v2

v2 = 10.53 m/s

diameter can be determine by using flow rate equation

r = 0.87 cm

d = 2*0.87 = 1.75 cm

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
