Why is the answer 0.118 when the answer given in the solution is 1.1?
Also why are litres converted to millilitres when litres are the SI Unit?
For Question 25:
Is specific gravity always in comparison to water?
For Question 36:
Why is there more friction in the middle of a moving fluid in comparison to the edges of a moving fluid? Wouldn't there be more friction at the edges of a moving fluid as they are closer to the edges of the vessel, so they would collide with the vessel more resulting in increased friction?
