Describe why mixtures of liquids and gases, even of the same substance, are NOT ideal gases. Describe which assumptions this mixture violates and draw plots comparing the behavior of these gases on P-v and T-v plots to support your argument. Water in a piston-cylinder system undergoes an isobaric heat addition process. It starts as a saturated liquid at 438.1 K (state 1) and then heat is added. Make sure to indicate the table you used for each of the questions below. What is the enthalpy at state 1? What is the enthalpy when the water reaches a saturated vapor state? What is the enthalpy when the water reaches 700 K? What is the phase?

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges

List 3 options on how to reduce knocking problens during engine process,

Consider a power plant with water as the working fluid that operates on an ideal rankine cycle. it has a net power output of 45mw. superheated steam enters the turbine at 7mpa and 500°c (h=3411.4 kj/kg; s=6.8 kj/kg k) and is cooled in the condenser at a pressure of 10 kpa by running cooling water from a lake through the tubes of the condenser at a rate of 2000 kg/s. (a) show the cycle on a t-s diagram (a right schematic is fine - you do not need to calculate the temperatures at each point); (b)-determine the work done by the turbine and the pump in kj/kg; (c)-the mass flow rate of water used by the power plant; (d)-the thermal efficiency of the cycle; (e)-the temperature rise of the cooling water. assume the cooling water is incompressible with cp 4.18 kj/kg°c.
