The bubble diameter has been expressed by Fritz as 1/2 b) D b = C d β 3/2 c) D b = C d β 5/2 d) D b = C d β 7/2

The bubble diameter has been expressed by Fritz as 1/2 b) D b = C d β 3/2 c) D b = C d β 5/2 d) D b = C d β 7/2 Correct Answer D b = C d β 1/2

C d is a constant which has been evaluated as 0.0148 for hydrogen and water bubbles. Where, C d is a constant, σ is surface tension of the liquid and β is the bubble contact angle measured through liquid in degrees.
