Explanation:
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
Permanent brain damage begins after only 4 minutes without oxygen.

No
Explanation:
He is actually still alive
Answer: False
Explanation: For implementation of the safety and the health program, there is high requirement of the employees because they are the people who will participate in the program and can make it successful.
Apart from the management and the leader, who are there to manage the program and lead the program as head by taking responsibility of other respectively, employees participation is required.Employees are referred as the people who will do the activities and also teach other about it.Thus, the statement in question is false.
