Question
The cylindrical tube of a spray pum cross-section of $6 \mathrm{~cm}^{2}$ one of which hanp o each of diameter $1 \mathrm{~mm}$. If the liquid flow 50 tube is $1.2 \mathrm{~m}$ per minute, then the speed $\mathrm{Th}_{\mathrm{I} / \mathrm{d}}$ of the liquid through the holes is speed of(a) $2.1 \mathrm{~m} \mathrm{~s}^{-1}$(b) $0.31 \mathrm{~m} \mathrm{~s}^{-1}$(c) $0.96 \mathrm{~m} \mathrm{~s}^{-1}$(d) $3.4 \mathrm{~m} \mathrm{~s}^{-1}$
Step 1
The cross-sectional area of the tube is given as $6 \, \text{cm}^2$, which is equal to $6 \times 10^{-4} \, \text{m}^2$. The diameter of each hole is given as $1 \, \text{mm}$, which is equal to $1 \times 10^{-3} \, \text{m}$. Show more…
