A building is 512 m high. What must be the minimum water pressure in a pipe at ground level in order to get water out of a tap in a restaurant on the top floor? Density of water is 1000 kg/m^3, assume the pressure on the top floor is 1 atmosphere (Patm=1.01 x 10^5 Pa). a. 5 x 10^6 Pa
b. 2 x 10^6 Pa
c. 1 x 10^6 Pa
d. 5 x 10^5 Pa
e. 1 x 10^5 Pa

Pressure =  5 x 10⁶ Pa

Explanation:

Given:

Height of building = 512 m

Find:

Pressure

Computation:

P2 = P1+dgh

P2 = 1 + (1000)(9.8)(512)

P2 = 51.2 atm

Pressure =  5 x 10⁶ Pa

there are no atoms

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
