Estimate the theoretical capacity of a traffic lane with one-way traffic flow at a stream speed of 45 kmph. Assume the average space gap between vehicles to follow the relation Sg = 0.278 Vt where V is the speed in kmph, t is the average reaction time 0.8 sec. Assume the average length of vehicles =5.0 m.
Detailed Solution for AIIMS CRE Civil JE/AE Mock Test- 9 - Question 15
speed V= 45 kmph

reaction time t = 0.8 sec

length of vehicles L = 5 m

space s = 0.278 Vt + L

= 0.278 x 45 x 0.8 + 5

= 10.008 + 5

= 15.008 m

theoretical capacity C = 1000V/S

= 2998.4

= 2998(say)

So theoretical capacity C = 2998 vehicles/hour/lane

Hence the correct answer is option B.

The drag force exerted by a fluid on a body immersed in the fluid is due to-
Detailed Solution for AIIMS CRE Civil JE/AE Mock Test- 9 - Question 27
Viscosity of fluid and the gravitational pull both exert a drag force on the body.

The drag force on an immersed object can be due to various reasons. It also depends on the direction of the object’s movement. Viscosity is the thickness of fluid that opposes the motion of the object. Gravity causes a ‘downward pull’ that slows horizontal movement. The pressure of the liquid on all sides of the object also hampers its motion.

Hence the correct answer is option D.
