1. Multiple choice question: choose the unique correct answer. Let X ~ N(0, 64). Then E($X^{2k+1}$), for any k = 0, 1, 2, ..., must be (a) greater than 0. (b) smaller than 0. (c) equal to 0. (d) depending on the value of k.
At a specific temperature and pressure, water can exist in different phases. It can be in a liquid phase, where it has a very low enthalpy. It can also be in a superheated phase, where it has a very high enthalpy. Water can have an enthalpy value between these two phases. For example, the enthalpy of water in the liquid phase (hf) is 417, while the enthalpy of steam is 2647. What is the phase of the water medium at 2000 kJ/kg? Can water enter the boiler in this phase in the Rankine cycle? Can the water medium be in a wet-steam phase at the inlet of the boiler in the Rankine cycle?
