Answer:
Rotary engine was early known by the name of internal combustion engine. It convert heat from a high pressure of combustion. The main advantage of rotary engine is that it can be operate with less number of vibration. It works on the principle of converting pressure into rotating motion. In rotary engine the expansion pressure is applied on the flank rotor.
Answer:
vehicle density = 28.205 veh/mile
flow rate = 0.909 veh/hr
Explanation:
given data
count n = 21
distance = 0.78 miles
speed = 52 mph
solution
we get here vehicle density that is express as
vehicle density = n ÷ distance ...............1
vehicle density = ( 21 + 1 ) ÷ 0.78
vehicle density k = 28.205 veh/mile
and
now we get here flow rate that is express as
flow rate = k × vs .................2
flow rate = 28.205 × ( 52 × 0.00062 ÷ 1m )
flow rate = 0.909 veh/hr
Answer:
a) probability of selecting working switch= (probability of A getting selected)x(working probability of A)+(probability of B getting selected)x(working probability of B)+(probability of C getting selected)x(working probability of C)=0.75/3+0.5/3+.25/3=0.5
b)its conditional probability p(A|B)=p(AnB)/p(B)=(0.75/3+0.5/3)/(0.75/3+0.5/3+.25/3)=5/6=0.833
