Maximum elemental U-value = 0.22 W/m2°C The insulation thermal conductivity = 0.03 W/m°C
Determine the minimum thickness of insulation need to be fixed above the newly proposed 6mm thick ceiling having k-value = 0.102 W/m°C

Answer: buoyancy forceexplanation: in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

The modern-day generator works on the principle of electromagnetic induction discovered by michael faraday in 1831-32. faraday discovered that the above flow of electric charges could be induced by moving an electrical conductor, such as a wire that contains electric charges, in a magnetic field.
