Streamline flow is more likely for liquids with (low density/high density) and high viscosity.

What will be the nature of flow of water from a circular tap, when its flow rate increased from $0.18 \mathrm{L} {\left(\min \right)}^{-1}$ to $0.48 \mathrm{L} {\left(\min \right)}^{-1}?$ The radius of the tap and viscosity of water are $0.5 \mathrm{cm}$ and ${10}^{-3} \mathrm{Pa} \mathrm{s}$, respectively. (Density of water : ${10}^3 \mathrm{kg} {\mathrm{m}}^{-3}$)

The platelets are drifting with the blood flowing in a streamline flow through a horizontal artery as shown below:

Artery is contracted in region $\mathrm{II}$. Choose the correct statement.

A cylindrical tank has a hole of $1{ \mathrm{cm}}^2$ in its bottom. If the water is allowed to flow into the tank from a tube above it at the rate of $70{ \mathrm{cm}}^3 {\mathrm{s}}^{-1}$, then the maximum height up to which water can rise in the tank is_________

Figure below shows a liquid being pushed out of the tube by a piston having area of cross section $2.0 {\mathrm{cm}}^2$. The area of cross section at the outlet is $10 {\mathrm{mm}}^2$. If the piston is pushed at a speed of $4 \mathrm{cm} {\mathrm{s}}^{-1}$, the speed of outgoing fluid is _____ $\mathrm{cm} {\mathrm{s}}^{-1}$
