Basics of aptitude and Mechanical engineering

Q1. Draw pump characteristics curve and explain.
Ans. 
Pump characteristics curve shows the relationship between flow rate and head developed by the pump.
• The curve is plotted between flow rate (x-axis) and head (y-axis).

• It helps in selecting the right pump for a particular application.

• The curve can be used to determine the operating point of the pump.

• The shape of the curve depends on the type of pump and impeller design.

• The curve can also show the efficiency and power cons...read more

Q2. Difference between CSTR and PFR, Pumps ,Heat Exchanger.
Ans. 
CSTR and PFR are types of reactors, pumps are used to move fluids, heat exchangers transfer heat between fluids.
• CSTR (Continuous Stirred Tank Reactor) has a constant volume and operates under steady-state conditions.

• PFR (Plug Flow Reactor) has a varying volume and operates under unsteady-state conditions.

• Pumps are mechanical devices used to move fluids from one place to another, like centrifugal pumps or positive displ...read more
