Answer:
Explanation:
Given
Pipe is lowered to the water [tex]h=90\ m[/tex]
Negative Pressure is applied to raise the water
Pressure is given by
[tex]P=\rho gh[/tex]
where [tex]P=pressure[/tex]
[tex]\rho =Density[/tex]
[tex]h=depth[/tex]
[tex]P=10^3\times 9.8\times 90[/tex]
[tex]P=8.82\times 10^{5}\ N/m^2\approx 8.82\ atm[/tex]
(b)8.82 atm is much lower than the vapor pressure of water
(c)The fact of applying a negative pressure of 8.74 below the vapor pressure of water
