Answer:
1113kN
Explanation:
The ouside diameter OD of the pipe is 61cm and the thickness T is 0.9cm, so the inside diameter ID will be:
Inside Diameter = Outside Diameter - Thickness
Inside Diameter = 61cm - 0.9cm = 60.1cm
Converting this diameter to meters, we have:
This inside diameter is useful to calculate the volume V of water inside the pipe, that is the volume of a cylinder:
The problem gives you the water density d as 1.0kg/L, but we need to convert it to proper units, so:
Now, water density is given by the equation , where m is the water mass and V is the water volume. Solving the equation for water mass and replacing the values we have:
With the water mass we can find the weight of water:
Finally we find the total weight add up the weight of the water and the weight of the pipe,so:
Converting this total weight to kN, we have:
