The water pressure in the mains of a city at a particular location is 270 kPa gage. Determine if this main can serve water to neighborhoods that are 25 m above this location.

Answer:

The Main can serve water to neighborhoods that are 25 m above this location.

Explanation:

From the question we are given that

             The water pressure is [tex]W_p = 270 \ kPa = 270 *10^3Pa[/tex]

              The  height  to serve water [tex]h= 25m[/tex]

Now assuming that the fluid is in-compressible

  Generally the density of water is [tex]\rho = 1000 kg/m^3[/tex]

The water pressure is mathematically represented as

       [tex]W_p = \rho g h_w[/tex]

Where [tex]h_w[/tex] is the height of water corresponding to the pressure [tex]P_g[/tex]

    Substituting values we have

              [tex]270*10^3 = (1000)(9.81)*h_w[/tex]

Making [tex]h_w[/tex] the subject of the formula

               [tex]h_w = 27.52m[/tex]

Looking this value of [tex]h_w[/tex] we see that [tex]h_w > h[/tex] which mean that the pressure a the mains is sufficient to supply the water to a height of [tex]25m[/tex]
