Answer:
The minimum gauge pressure is 0.4969 atm.
Explanation:
Given that,
Density = 1040 kg/m³
Height = 4.94 cm
We need to calculate the pressure
Using formula of pressure

Where,
=density
h = height
Put the value into the formula


Pressure in atmospheres


Hence, The minimum gauge pressure is 0.4969 atm.
To measure the fluids that you will be using such as water or other chemicals if your mixing them and they have to be precise measurements
They'll vibrate at their characteristic resonant frequency. That depends on the material the object is made of and its shape.
