1- Work out the entire cross sectional area of pipe.
2- Work out the entire volume of pipe with the following formula.
volume = total cross sectional area x length of pipe.
volume = total cross sectional area x length of pipe.
3- Work out the weight of pipe with the following formula.
weight of pipe = volume of pipe x unit weight of pipe materials.
weight of pipe = volume of pipe x unit weight of pipe materials.
Example:The Calculation for Find Out the Weight of this Cast Iron Pipe is Made on the Basis of the Following Dimensions
Internal diameter of the pipe = 10 cm
External diameter of the pipe = 14 cm
Length of the pipe = 5 meters
External diameter of the pipe = 14 cm
Length of the pipe = 5 meters
As we know from the above formula :
Volume = cross sectional area x length
V = Ï€ (D2 – d2)/4 x L
V = Ï€ (D2 – d2)/4 x L
After putting the values, we get the following :
V = Ï€(0.142 – 0.102)/4 x 5 (covert centimeter to meter)
V = 0.0376991 cu.m
So, weight = 0.0376991 x 7200 (as unit of cast iron is equivalent to 7200 kg/m3)
V = 0.0376991 cu.m
So, weight = 0.0376991 x 7200 (as unit of cast iron is equivalent to 7200 kg/m3)
Weight of pipe = 271.433 kg
