Cavitation can take place in case of

Cavitation in centrifugal pumps

• Cavitation is likely to occur at the inlet to the pump
• Since the pressure there is the minimum and is lower than the atmospheric pressure the formation of bubbles or cavities in liquid, developed in areas of relatively low pressure around an impeller
• The imploding or collapsing of these bubbles trigger intense shockwaves inside the pump, causing significant damage to the impeller and/or the pump housing

• A vessel contains 20 litres of acid. 4 litres of acid is taken out of the vessel and replaced by the same quantity of water. Next 4 litres of the mixture are with, drawn, and again the vessel is filled with the same quantity add left in the vessel with t
• Train A takes 45 minutes more than train B to travel a distance of 450 km. Due to engine trouble speed of train B falls by a quarter, so it takes 30 minutes more than Train A to complete the same journey. What is the speed of Train A (in km/hr)?
