Question

I need help with these 2 problems and all of their parts.

Combined cycle power plants are common because of their high efficiency and scalability. They typically combine a
gas turbine cycle (the Brayton Cycle) with a steam turbine cycle (the Rankine Cycle) [1]. This project is to determine
the operating efficiency and profitability of a realistic combined cycle power plant. The power plant is as follows:
1. A natural gas-fired Brayton Cycle with mair,Br = 0.72 kg s.
(a) Ambient air at 1.00 bar and 300 K is taken in.
(b) A compressor with an inlet-to-outlet pressure ratio of 1:19.
(c) Intercooling, decreasing the temperature by AT = -150 K.
(d) A second-stage compressor with a pressure ratio of 1:5.
(e) Regeneration between the compressor and the combustor, increasing the temperature by 85 K
(f) Combustion at constant pressure to 1800 K.
(g) A two-stage turbine system with reheat between the stages. Reheat occurs at 12.4 bar and raises the
temperature to 1600 K.
(h) Discharge to a heat exchanger at 1.50 bar, where waste heat is used to warm steam for the Rankine Cycle.
The outlet temperature from this heat exchanger is 600 K.
(i) From that heat exchanger, discharge to the regeneration heat exchanger in part le.
2. A water-steam Rankine Cycle with mwater,Ra = 1.06 kg s-1.
(a) A two-stage turbine system, with reheat between the stages.
The first turbine inlet is at 560 °C and 160 bar. Reheat occurs at 40.0 bar up to 52o °C. The second-stage
turbine outlet is 2.00 bar.
(b) Cooling at constant pressure in a condenser via heat exchange with ambient air to saturated liquid.
The air used in condenser cooling must not exceed 400 K when it is released from the power plant.
(c) A pump from the low-side pressure to the high-side pressure.
(d) Heating in a boiler at constant pressure, using the waste heat from the Brayton Cycle in a first stage and

If the student is pulling the free end with a velocity of 2.75 ft/s. a) What is the mechanical advantage between the student and the pizza boxes? Hint: The link between pulleys 1 and 4 is rigid (meaning that they must move together. This is the key to solving this problem! b) What is the velocity of the pizza boxes?

Problem- Cargo ships can cause a lot of air pollution.Solution- to use nuclear powered ships since they hold a lot of energy and can travel for long distances. How it will work is that it will need a nuclear reactor at the bottom of the boat to heat up the water and then turn it to electricity to power the boat. The boat will be made out of graphene which is a tough material to avoid any leaks in the boat. It will also contain many control rods because nuclear power is so powerful that it can create to much energy to handle. With control rods, you can slow down this process and keep it in a controlled manner. Since cargo ships are already is the ocean, there will be no need for any extra materials to make it work. -Do you think this will work? Why/Why not? -What do you think is wrong with it/ How can this be improved? Please send this to someone else I need to record 50 responses for a science project. Thank you!

Part 2 Set up a spreadsheet solution to this problem. This will require that you derive one formula to express the relationship between the friction coefficient, the spring constant, and the spring compression; and a second formula to find the cost of using different slide and spring types. Set up your spreadsheet as shown below. You can fill in the "Acceptable?" column manually, rather than using a formula.
