0.05 kg of steam at 15 bar is contained in a rigid vessel of volume 0.0076m3 what is the temperature of the steam?if the vessel is cooled until the pressure in the vessel is 11 bar calculate the dryness fraction of the steam and the total heat rejected?

Is this statement true or false and why?. 'The colder the fridge evaporator, the more cooling power it provides

Solve the following modified entropy optimization problem. For ease of solution you can solve the problem ignoring the non-negativity constraints on p and q and then verify that they are satisfied.

min p log p +2qlog q

subject to p+q = 1

p,q >=0

min p log p +2qlog q

subject to p+q = 1

p,q >=0

Consider the following problem related to entropy maximisation in information theory. For ease of solution you can solve the problem ignoring the non-negativity constraints on p and q and then verify that they are satisfied.

min p log P + q log q

subject to p+q =1

p,q.>=0

i. Solve the primal problem directly

ii. Obtain the dual problem and solve it. Verify it gives the same answer as the primal problem.

iii. By doing an internet search or looking up textbooks, explain why this problem would be

called an “entropy maximisation” problem.

A piston-cylinder device contains 1.38 kg of refrigerant-134a at -10 oC. The piston that is free to move has a mass of 16 kg and a diameter of 11.18 cm. The local atmospheric pressure is 84 kPa. Now, heat is transferred to refrigerant-134a until the temperature is 90 oC. Determine (a) the final pressure (kPa), (b) the change in the volume of the cylinder (m3), and (c) the change in the enthalpy of the refrigerant-134a (kJ/g).
