If tank of 10m height is filled half what will be pressure at bottom of tank

no idea - what is it filled with?

what is the weight of a column of fluid ?

weight=massdensity*area*height *9.8N/kg

pressure=weight/area=massdensity*9.8 *10

so, put in the massdensity of whatever you have filled it with, in kg/m^3, and you have it.

To determine the pressure at the bottom of a tank that is filled halfway, we can use the concept of hydrostatic pressure. Hydrostatic pressure is the pressure exerted by a fluid at rest due to the force of gravity. The pressure at any point within a fluid depends on the height of the fluid above that point.

In this case, we have a tank with a height of 10 meters that is filled halfway, which means it has a fluid column height of 5 meters.

To calculate the pressure at the bottom of the tank, we can use the formula for hydrostatic pressure:

Pressure = density × gravity × height

First, we need to know the density of the fluid being used to fill the tank. Let's assume the fluid is water, which has a density of approximately 1000 kilograms per cubic meter (kg/m³).

Next, we need to know the acceleration due to gravity, which is approximately 9.8 meters per second squared (m/s²).

Using these values, we can now calculate the pressure at the bottom of the tank:

Pressure = density × gravity × height
= 1000 kg/m³ × 9.8 m/s² × 5 m

By substituting the known values into the equation, we can calculate the pressure at the bottom of the tank:

Pressure = 1000 kg/m³ × 9.8 m/s² × 5 m
= 49,000 Pascal (Pa)

Therefore, the pressure at the bottom of the tank when it is filled halfway is 49,000 Pa.
