Answer:
Amount reduction is 29.06 gal/year
Cost of reduction is $90.09 / year
Explanation:
Assume The effect of reduction of the frontal area on the drag coefficient is
negligible
Given that:
The drag coefficient () = 0.4 for a passenger car.
A = frontal area of car = 18 ft²
Velocity (V) = 55 mile per hour = (55 × 1.4667) ft/s = 80.6685 ft/s, density of air (ρ) = 0.075 lbm/ft³
The frontal drag force can be calculated by:
The amount of work done to overcome this drag force is calculated by:
d = 12000 miles per year
and the required energy input is:
Heating value (HV) = 20000 Btu/lbm
Amount of fuel =
Cost of fuel = Amount of fuel × Price of fuel = 11.1 ft³/year × ($3.1/gal) × (7.4804 gal / 1 ft³) = $257.4 per year.
The percent reduction in the fuel consumption due to reducing frontal area (reduction ratio) is given by:
Reduction ratio =
Amount reduction = Reduction ratio × Amount of fuel = 0.35 × 83.03 gal/year =29.06 gal/year
Cost of reduction = Reduction ratio × cost of fuel = 0.35 × $257.4 = $90.09 / year

Answer:
(a)- cutting tools
Explanation:
High speed steel is the cutting tool material .It is widely used in the production process.it also represent as HSS.High speed steel is made from heat treatment process of steel .
The high speed steel have following compositions
1.Tungsten - 18 %
2.Chromium - 4%
3. Vanadium- 1 %
4.Carbon - 0.7 %
5.Iron - 76.3 %
So the option a is correct.
(a)- cutting tools
Whiteness is often used as a derogatory term to describe Caucasian culture. This influences our society by promoting anti-White hatred.
