Pick out the wrong statement pertaining to ‘Horton sphere’ used for the storage of liquid ammonia?
AHorton sphere is used for the storage of liquid at sub-zero temperature at very high pressure upto 200 kg/cm2
BThickness of spherical shell is half that of the cylindrical vessel under same operating pressure condition. Besides, the ratio of surface area to volume is less for sphere than any other shape; hence insulation required is less
CDiameter of Horton sphere is normally 6 to 25 metres and it is supported by 6 to 12 nos. tubular or rolled section column
DHorton sphere is used for the storage of gases and volatile liquid at a moderate pressure of 1 to 10 kg/cm2
Correct answer
A. Horton sphere is used for the storage of liquid at sub-zero temperature at very high pressure upto 200 kg/cm2
Explanation
The correct answer is Horton sphere is used for the storage of liquid at sub-zero temperature at very high pressure upto 200 kg/cm2.
