Question 3. The purchase price of a natural gas-fired commercial boiler (capacity X) was $181,000 eight years
ago. Another boiler of the same basic design, except with the capacity 1.42X, is currently being considered for
purchase. If it is purchased, some optional features presently costing $28,000 would be added for your
application. If the cost index was 162 for this type of equipment when the capacity X boiler was purchased and
is 221 now, and the applicable cost capacity factor is 0.8, what is your estimate of the purchase price for the
new boiler?
Hint: Use both indexing and power-sizing methods.

1. (More practice from Monday) A 90° elbow in a horizontal pipe is used to
direct a flow of oil (SG = 0.87) upward at a rate of 40 kg/s. The cross-
sectional diameter of the elbow is a constant 20 cm. The elbow discharges at
A into a large holding tank where the level of oil is 1.8 m above A. The
50 cm
"weight" of the elbow and the oil in it is 50 kg. Determine (a) the gage
pressure at the inlet of the elbow and (b) the anchoring force needed to hold
the elbow stationary. Take the momentum-flux correction factor to be 1.03
40 kg/s
at both the inlet and the outlet.

QUESTION 20
A single-stage, single-acting air compressor with runs at speed 600 rpm. It has a polytropic index of
1.26. The induced volume flow rate is 7.2 cubic meters per min and the air must be delivered at a
pressure of 668 kPa. The free air conditions are 101.3 kPa and 18 degrees Celsius. The clearance
volume is 6% of the stroke volume and the stroke/bore ratio is 1.6/1. Calculate the delivery air.

About 2,200 years ago, one of the most famous mathematicians in history made a major discovery. The
mathematician was Archimedes, who was presented with a problem by King Hiero Il of Syracuse in Sicily.
Save & Exit
The king had given a bar of gold to a jeweler and ordered him to make it into a crown. After receiving the
crown, the king suspected that the jeweler had replaced some of the gold with an equal weight of a cheaper
metal like silver and kept the remainder of the gold for himself. The king had no way to determine whether
this was true, so he gave the crown to Archimedes and asked him to devise a way to find out.
At the time, Archimedes knew that gold was more dense than silver. So, if the volume of…

QUESTION 2
A company needs to choose one supplier for a particular type of silicon wafer used'in the production of
semiconductors. The company has three options. Supplier A sells the silicon wafers for $2.50 per wafer,
independently of the number of wafers ordered. Supplier B sells the wafers for $2.40 each but does not
consider an order for less than 2,000 wafers. Supplier C sells the wafers for $2.30 each but does not accept
an order for less than 3,000 wafers. Assume an order setup cost of $100 and an annual requirement of 20,000
wafers. Assume a 20% annual interest rate for holding cost calculations.
a. Which supplier should be chosen to minimize the total annual cost for the wafers, and what is the
optimal order quantity?
b. If the replenishment lead time for wafers…

Hint. Both power-sizing and indexing will be used. Ć + Question 3. The purchase price of a natural gas-fired commercial boiler (capacity X) was $181,000 eight years ago. Another boiler of the same basic design, except with the capacity 1.42X, is currently being considered for purchase. If it is purchased, some optional features presently costing $28,000 would be added for your application. If the cost index was 162 for this type of equipment when the capacity X boiler was purchased and is 221 now, and the applicable cost capacity factor is 0.8, what is your estimate of the purchase price for the new boiler? Hint: Use both indexing and power-sizing methods. 88 Illinois State University: TEC 330 001 FA2022 - Applied Economic Analysis For...arrow_forward11)arrow_forward

(More practice from Monday) A 90° elbow in a horizontal pipe is used to direct a flow of oil (SG = 0.87) upward at a rate of 40 kg/s. The cross- sectional diameter of the elbow is a constant 20 cm. The elbow discharges at A into a large holding tank where the level of oil is 1.8 m above A. The 50 cm "weight" of the elbow and the oil in it is 50 kg. Determine (a) the gage pressure at the inlet of the elbow and (b) the anchoring force needed to hold the elbow stationary. Take the momentum-flux correction factor to be 1.03 40 kg/s at both the inlet and the outlet. Activar Windows Ve a Configuración para activar Windows.
