Air flows through a converging-diverging nozzle/diffuser. Assuming isentropic flow, air as an ideal gas, and constant specific heats determine the state at several locations in the system Note: The specific heat ratio and gas constant for air are given as k=1.4 and R=0.287 kJ/kg-K respectively. --Given Values-- Inlet Temperature: T1 (K)= 366 Inlet pressure: P1 (kPa) = 496 Inlet Velocity: V1 (m/s) = 99 Area at inlet (cm^2) = 8.7 Mach number at the exit = 1.7 a) Determine the...

A steam power plant design consists of an ideal Rankine cycle with reheat and regeneration. Steam enters Turbine 1 at P1 and T1 at the rate of m1 and exits at P2. A fraction (y') of the steam exiting Turbine 1 is diverted to a closed feedwater heater while the remainder is reheated to T3 before entering Turbine 2. A fraction (y'') of the steam exiting Turbine 2 at P4 is diverted to an open feedwater heater while the remainder...
Thermodynamics Ideal Gas
Air confined to one side of a rigid container divided by a partition, as shown in Fig.2.The outer side is initially evacuated.The air is initially at p1=5 bar,T1=500 K, and V1= 0.2m3. When the partition is removed, the air expands to fill the entire chamber. Measurements show that V2=2V1and p2=p1/4.Assuming the air behaves as an ideal gas, determine (a) the final temperature, in K, and (b)the heat transfer, kJ.

A combined cycle gas turbine / vapor power plant uses the turbine exhaust as the energy source for the boiler. Each power system uses a single turbine. The gas power system is modeled as an ideal air-standard Brayton cycle. The vapor power system is modeled as an ideal Rankine cycle. Given specific operating conditions determine the temperature and pressure at each state, the rate of heat transfer in the boiler, the power output...
