Consider a water pump receives liquid water at 15°c and 100 kpa and send it out through a short pipe with anozzle with 1cm diamerter at 100 kpa. determine exit velocity and mass flowrater when the power of pump is 1kw. kinetic energy in pipe and assume internal energy is constant.

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
