Calculate the pressure of water in a well if the depth of the water is 10m

Kryger [21]

Answer:

P= phg

so:- the height is 10m

density of water 1000 kg/m3

gravity is 9.8m/s2

P=1000 kg/m3*10m*9.8m/s2

=98000Pa

=98KPa

The highest waterfall in the world is the Salto Angel in Venezuela. Its longest single falls has a height of 807 m. If water at

valentina_108 [34]

Answer:

Temperature at the bottom will be 19.18°C

Explanation:

We have given height h = 807 m

Temperature at the top $=17.3^{\circ}C$

Specific heat of water c = 4200 $J/kg/^{\circ}C$

From energy conservation

Kinetic energy at the bottom = potential energy at the top

So $mc\Delta T=mgh$

$\Delta T=\frac{gh}{c}=\frac{9.8\times 807}{4200}=1.88^{\circ}C$

So temperature at the bottom = 17.3+1.88 = 19.18°C
