Question

A 5 m long vertical tube having cross sectional area of 200 cm^2 is completely filled with water at room temperature. Calculate the mass of water present in the tube. Density of water at room temperature is 1000 kg/m^2

Answer 1

mass = 100kg

Step-by-step explanation:

Hello! In order to calculate the mass, we first have to calculate the volume of the tube.

For this, we have the area (A) and the length (L) of the tube.

V = A * L

A = 100cm2 * (1m2 / 10000cm2) = 0.02m2

L = 5m

V = 0.02m2 * 5m = 0.1m2

Then we can calculate the area from the density.

Density = mass / volume

mass = density * volume = 1000 (kg / m3) * 0.1m3

mass = 100kg
