Q3. How to calculate Belt length
Ans. 
Belt length can be calculated using the formula: L = 2C + (πD)
• Measure the distance around the pulleys (C)

• Measure the diameter of the larger pulley (D)

• Use the formula L = 2C + (πD) to calculate the belt length

• For example, if C = 30 inches and D = 10 inches, then L = 2(30) + (3.14)(10) = 60 + 31.4 = 91.4 inches

Q4. Where, firstly steam is enter in Turbine
Ans. 
Steam enters the turbine at the high-pressure stage.
• Steam enters the turbine at the high-pressure stage to maximize energy extraction.

• The high-pressure steam is directed into the turbine blades, causing them to rotate.

• The steam then passes through multiple stages of the turbine, gradually losing pressure and expanding.

• At each stage, the steam's energy is converted into mechanical work to drive the turbine.

• Finally, the ...read more
