A U-shaped irrigation canal is dug into the ground such that the bottom of the channel has a semi-circular cross section with a diameter of 2.0 m. A sluice gate having an overall height of 5 m can be lowered vertically into the channel to block the flow of water. Water partially fills the channel up to the horizontal line B-B. Determine the moment exerted by the water about the line A-A at the upper edge of the sluice gate. Problem

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

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.
