A 2-m3 rigid insulated tank initially containing saturated water vapor at 1 MPa is connected through a valve to a supply line that carries steam at 400°C. Now the valve is opened, and steam is allowed to flow slowly into the tank until the pressure in the tank rises to 2 MPa. At this instant the tank temperature is measured to be 300°C. Determine the mass of the steam that has entered and the pressure of the steam in the supply line. The initial and final properties of steam in the tank are v1 = 0.19436 m3/kg, u1 = 2582.8 kJ/kg, v2 = 0.12551 m3/kg, and u2 = 2773.2 kJ/kg. Solve using appropriate software.

The mass of the steam is kg.

The pressure of the steam is kPa.

QUESTIONS:

Net present value (NPV) of the wind farm project
In order to make this calculation, we need to convert some of the information we have
into annual figures:
1. What are the O&M costs in euro for each year (€/year)?
2. What is annual revenue from selling the electricity (€/year)?
3. What is the annual net income (€/year)?
4. What is the net present value of this wind farm project(€)? Hint: when calculating
with NPV function don't forget to extract the decommissioning cost from the last
years net income.

DATA:
The basic information about the wind farm:
Wind farm capacity (MW) 50
Capital investment (€) 65 000 000
Period of operation (years) 20
Decommissioning costs (€) 3 000 000
O&M costs (€/kWh) 0.0091
Annual energy production (kWh) 110 000 000
Electricity selling price, tariff (€/kWh) 0,075
Annual discount rate (%) 8

Can you please help me solve this engineering economics question, I am really confused.

Please be very specific when explaining your solution & show all formulas used.

Thank you,

A heat exchanger with 1 body - 4 pipe passages and 109 pipes (2.6 cm diameter each, 4 m long thin wall per passage) at each passage will be used to heat the air. The water enters the pipes with a mass flow of 8 kg / h at 350 K temperature and the air enters the body with a mass flow of 18 kg / h at a temperature of 15 C. The pollution factor of the sediment formed inside the pipe over time is 0.0026 m2K / W. The transport coefficients on the inner and outer surfaces of the pipes are estimated at 450 and 200 W / m2K, respectively. Using specific temperatures at 25 C for air and water

a-) The effectiveness of the heat exchanger by drawing the shape of the problem,

b-) Heat transfer rate (kW),

c-) Calculate the outlet temperatures (C) of the water and air and show the temperatures in the T_L diagram.

We want to determine spesifications of very toxic fuel especially the particle diameters. After some studying we claim that the particle diameter is dp, exit speed is U, the liquid viscosity is u, surface tension is Y, density is p, the diameter of spraying injector exit is D. For a secure experiment we need to work with water. Design an experiment with water and determine the required conditions. Finally, for toxic fuel use the results of experiment for determining spesifications (especially the partical diameter) with mathematical expressions use dimensionless numbers if needed.
