Question

a) An object weighs 0.027 kg in air. Its material has a density of 2.7 x 103 kg/m3. What would be the apparent weight of the object if it were immersed in a liquid of 900 kg/m3?

Answer 1

Answer:

For air at 20°C = 293 K and 7000 Pa, the density is ρ = p/RT = (7000)/[(287)(293)] = 0.0832 kg/m3. From Table A-2, its viscosity is ...
