What is capillary break?
What will be an ideal response?
Water can be sucked into tiny pores of a material due to capillary forces, referred to as capillary suction. Capillary suction can be so strong as to suck water up against the force of gravity. Capillary suction also occurs in a narrow joint between two components. Because it occurs only in tiny spaces, capillary suction can be prevented by
increasing the width of the space somewhere in the middle of the joint.

A garden hose with the water valve shut and the nozzle closed sits in the sun, full of liquid water. Initially, the water is at 10°C and 6 bar. After some time the temperature of the water rises to 40°C. Owing to the increase in temperature and pressure and the elasticity of the hose, the internal diameter of the hose increases by 0.35%. Estimate the final pressure of the water in the hose.
