A closed, rigid tank contains 2 kg of water, initially a two-phase liquid-vapor mixture at 70 °C. Heat transfer occurs until the tank contains only saturated vapor which $v$ = 2.045 m³/kg. For the water, locate the initial and final states on a sketch of the T-v diagram and determine the heat transfer, in kJ.

1. A gas turbine plant consists of two turbines. One turbine is used to drive compressor and the other power turbine both having their own combustion chamber. Air enters the compressor at 1 bar and $ 288 \mathrm{~K} $ and is compressed to 8 bar with an isentropic efficiency of $ 76 \% $. Due to heat added to air in the combustion chamber, the inlet temperature to both turbines is $ 900^{\circ} \mathrm{C} $. The isentropic efficiency of turbines is $ 86 \% $ and mass flow rate of air is $ 23 \mathrm{Kg} / \mathrm{s} $. The calorific values of fuel is $ 42000 \mathrm{~kJ} / \mathrm{Kg} $. Draw the schematic diagram of the plant and T-s diagram. Calculate the output of the plant and thermal efficiency if mechanical efficiency is $ 95 \% $ and generator efficiency is $ 96 \% .\left(C_{p a}=1.005 \mathrm{~kJ} / \mathrm{kgK}, C_{p g}=1.128 \mathrm{~kJ} / \mathrm{kgK}\right. $, ratio of specific heats are 1.4 for air and 1.34 for gas).

Your Uncle Sean has a wool business in Ireland. The company first shears the sheep and then washes the wool, at which point it has wool fiber and crude lanolin. Then the wool fibers are further processed to make yarn, and the crude lanolin is processed further to make lanolin cream. Uncle Sean asks for your help in allocating costs and determining profitability. Here is the information he sent: Cost Joint process cost: $1000 Further processing cost (wool fiber to yarn): $500 Further processing cost (crude lanolin to cream): $600 Wool Fiber Crude Lanolin Wool Blend Yarn Lanolin Cream Quantity produced (pounds): 100 Quantity sold (pounds): 150 Sales value per pound: $3 Crude Lanolin Quantity produced (pounds): 40 Quantity sold (pounds): 60 Sales value per pound: $5 Wool Blend Yarn Quantity produced (pounds): 80 Quantity sold (pounds): 80 Sales value per pound: $10 Lanolin Cream Quantity produced (pounds): 50 Quantity sold (pounds): 0 Sales value per pound: $13
