Question

Briefly describe about ‘Expanding ring experiment’ and ‘Taylor cylinder test’ (testing method and objectives of the test)

Answer 1

Expanding ring experiment:

The objective of this experiment is to show the expansion of metals on heating.

Method: for this experiment we need one metallic ball and a ring such that the ball fits through the ring . The method is very simple. First check that the ball fits through the ring . Now heat the ring with the flame and try to fit it again through the ball .

Conclusion : second time it will not fit because the metallic ring expands on heating.

Taylor cylinder test:

The main objective of this expetiment is to find the effect of area of cross section on flow capacity . Here by using different cylinders having different cross sections we can conclude that large A/R gives lower gas velocity and higher flow capacity . while small A/R gives higher gas velocity and lower flow capacity.
