Why is it important that ironworkers wait to begin work until after cement masons are finished with their job?
cement is an important component of iron.
for most buildings, iron is used to encase the cement.
constructing a building's framework requires a solid foundation
it is easier for cement masons to correct errors in their work than it is for ironworkers

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

Condition monitoring is a major component of. (clo4) a)- predictive maintenance. b)-preventive maintenance c)-proactive maintenance d)-reactive maintenance.

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
