Shown in Fig. P2.87 is a cogeneration power plant operating in a thermodynamic cycle at steady state. The plant provides electricity to a community at a rate of 80 MW. The energy discharged from the power plant by heat transfer is denoted on the figure by Q out . Of this, 70 MW is provided to the community for water heating and the remainder isdiscarded to the environment without use. The electricity isvalued at $0.08 per kW h. If the cycle thermal efficiencyis 40%, determine the (a) rate energy is added by heattransfer, Qin , in MW, (b) rate energy is discarded to theenvironment, in MW, and (c) value of the electricitygenerated, in $ per year.
CFD Lab: Ofﬁce Hours 10-12pm Room 160A Grades: 3 or 4 quizzes, 4 reports, attendance. We will ﬁrst be going through the basic to understand what we are going to be using the ﬁnite element analysis for. Applications CFD: 1. Meteorology 2. Aerospace 3. Roto-Dynamic Machines 4. Hydrodynamics (Ships) 5. Bio ﬂuidics (Blood ﬂow through arteries, veins, & heart) Intro to CFD: Purpose - To predict ﬂuid ﬂow, heat & mass transfer, chemical reactions, and related phenomena by solving numerically the set of governing mathematical equations. We use a simpliﬁcation of the Stokes Equation in CFD. Steps: • Problem Identiﬁcation ◦ Deﬁne Goals ◦ Identify Domain • Pre-Processing ◦ Geometry ◦ Mech ◦ Physics ◦ Solver Settings • Solve ◦ Compute Solu
