what Should diameter of Water Drop So That axis Pressure Inside Is 80n/m2

Answer 2

⠀⠀Ꮯσrrєct quєѕtíσn↓

$\sf{what \: should \: be \: the \: diameter \: of \: a \: water \: drop} \: \\ \sf{ so \: that \: excess \: pressure \: inside \: it \: is \: 80 N/m^2?} \\ \sf{(Surface \: tention \: of \: water \: = 7.27 × 10 ^{ - 2} N/m}$

⠀⠀⠀『Ꭺnѕwєr 』

$\large \bf \underline \red{Given \: :}$

$\rightarrow \sf \bold{p_1 - p_0 = 80N/m}$

$\implies \sf{T = 7.27× 10 ^{ - 2} N/m}$

$\bf \underline\green{we \: have,}$

$\rightarrow\sf(p_1 - p_0) = \large \frac{2T}{r}$

$\sf \therefore \: r = \frac{2T}{p_1 - p_0} \\ \\ \sf= \frac{2 \times 7.27 \times {10}^{ - 2} }{80} \\ \\ \sf= 1.8 \times {10}^{ - 3}$

$\bf \red\therefore \bf \:{ d \: = 2r = 3.6mm}$
