Amanometer that is open to the atmosphere is used to measure the pressure in a tank. the working fluid is water with a density of 1000 kg/m3 and the fluid in the tank has a density of 2300 kg/m3. the tank fluid level is 60 mm above the base of the manometer and the water level is 1.2 m above the base. what is the pressure in the tank?

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.

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.

Vibration monitoring this technique uses the noise or vibration created by mechanical equipment and in seme cases by plant systems to detemine their actual condtion. a)- true b)- false
