The bubble diameter at the time of detachment from the surface can be worked out from the relation proposed by Fritz and is given by(Where, β is the angle of contact)

• A. C d β [2 σ/g (p t – p v)]
• B. C d β [2 σ/g (p t – p v)]^3/2
• C. C d β [2 σ/g (p t – p v)]^1/2
• D. C d β [2 σ/g (p t – p v)]^5/2
