A cylindrical tank of methanol has a mass of 40 kgand a volume of 51 L. Determine the methanol’s weight, density, and specific gravity. Take the gravitational accelerationto be 9.81 m/s2. Also, estimate how much force is needed toaccelerate this tank linearly at 0.25 m/s2.

Weight  W = 392.4 N

Density   = 784.31

Specific gravity S = 0.78431

Force required F = 10 N

Explanation:

Given data

Mass (m) = 40 kg

Volume (V) = 0.051

Weight W = m × g

⇒ W = 40 × 9.81

⇒ W = 392.4 N

This is the weight of the methanol.

Density =

⇒ =

⇒ = 784.31

This is the density of the methanol.

Specific gravity (S) =

⇒

⇒ S = 0.78431

This is the specific gravity of the methanol.

Force needed to accelerate this tank F = ma

⇒ F = 40 × 0.25

⇒ F = 10 N

This is the force required to accelerate the tank.
