How to make condenser, types of condenser, materials and formulas to find out its properties, please elaborate everything about condenser.

The 40 lb plank A rests on the 30 lb block B as shown in Figure 5. The coefficient of static friction between the plank and the block is μ_AB = 0.35 and between the block and the ground is μ_BD = 0.25. Determine the largest force P that can be applied to the plank without causing motion. Report your answer in lbs but do not enter units. Neglect the thickness of the plank. Consider and show all possibilities of motion.

1. You are to do a preliminary design study for a small demonstration steam turbine power plant.
- Steam will be provided by a small steam generator fired by natural gas.   - Your system will take in steam at 30 bar and 400 oC.
- The steam passes through a two stage turbine. At a pressure of 10 bars, the steam leaves the first stage of the turbine and will pass through a reheat loop in the steam generator which will boost the temperature back up to 400 oC at this pressure. The steam will then enter the second stage of the turbine.
- When the steam leaves the turbine, the quality should be at least 95% at the turbine exit / condenser inlet.
- The design condenser pressure is 0.70 bar.   
- Heat is removed from the condenser and rejected to the environment through a cooling tower.

For the following parts use the design turbine power output of 2.5 kW.
d) What mass flow rate is required? (10 pts)

e) At what rate must heat be produced by natural gas burners in the steam generator to produce the steam at the turbine inlet, and how much heat must be produced to reheat the steam between the stages? For a heating rate range of 950-1150 BTU/scf and a cost of $8 per 100 cubic feet, what is the fuel cost per hour to run this unit? (10 pts)

f) What is the feed water pump power demand, and what is the BWR? (10 pts)
