What is the liquid density in a manometer, if the difference in the li...
Liquid density in a manometer can be calculated using the equation:
Density = Pressure difference / (g * height difference)

Given:
Difference in liquid levels in the manometer tubes = 1.35 m
Differential pressure between the tubes = 7.85 kPa

We need to convert the differential pressure from kPa to Pa:
7.85 kPa = 7.85 * 10^3 Pa

Let's assume the acceleration due to gravity as g = 9.8 m/s².

Now we can substitute the values into the equation:
Density = (7.85 * 10^3 Pa) / (9.8 m/s² * 1.35 m)
= (7.85 * 10^3) / (9.8 * 1.35) kg/m³
≈ 578.43 kg/m³

Since the given options are in different units, we need to convert the density to the appropriate unit.

1 kg/m³ = 0.001 g/cm³
1 kg/m³ = 0.001 Mg/m³
1 kg/m³ = 0.001 Kg/dm³

So, the density in the manometer is approximately 578.43 kg/m³.

Converting this to the given options:
578.43 kg/m³ = 578.43 * 0.001 g/cm³ ≈ 0.578 g/cm³
Therefore, the correct answer is option 'C' - 0.59 Mg/m³.
