Solution:
Given Information,
Heat input is ( ) = 5.5 ×
Btu/h
Combustion efficiency of the boiler () = 0.7
Combustion efficiency after turn up () = 0.8
Operation Hour (t) = 5200h
Unit cost (c) =
Calculate heat output from the boiler =
x
= 5.5 x x 0.7
= 3.85 x Btu/h
Calculate the heat input to the boiler after the tune-up
=
/
= 3.85 x / 0.8
= 4.8125 x Btu/h
Calculate the saved energy after the tune-up
=
-
= 5.5 x - 4.8125 x
Btu/h
= 0.6875 x Btu/h
Calculate the annual energy saving ( )
=
x t
= ( 0.6875 x Btu/h ) ( 5200 hr/yr)
= 3575 x Btu/h
Calculate the annual cost saving
Annual cost saving = x Unit cost
= 3575 x Btu/h x
= 82225
Answer:
$489,512.15
Explanation:
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future value
P = Present value
R = interest rate
N = number of years
We are supposed to determine the present value
Present value is the sum of discounted cash flows
Present value can be calculated using a financial calculator
Cash flow in year 1 = 84,000
Cash flow in year 2 = 113,000
Cash flow in year 3 = 125,000
Cash flow in year 4 = 130,000
I = 6%
PV = 387,739.47
387,739.47(1.06)^4 = $489,512.15
To find the PV using a financial calculator:
1. Input the cash flow values by pressing the CF button. After inputting the value, press enter and the arrow facing a downward direction.
2. after inputting all the cash flows, press the NPV button, input the value for I, press enter and the arrow facing a downward direction.
3. Press compute
