Explanation:
Single Unit Truck ESAL = 43.38 + 5.16 = 48.54
Semi Unit Truck ESAL = 43.38+ 6.00+7.4 = 56.78
So total ESAL's during design life = (400*48.54 + 350*56.78)*365*10/18000 = (19416+19873)*3650= 3939
Kindly check the attached image
Here
Reliability = 95% = 0.95, therefore ZR = -1.645, S0 = 0.4, MR = 18
Delta PSI = 4.2-2.5= 1.7
Resilient Modulus = 18000 psi, So MR = 18
Assume SN = 3.0 for flexible pavements
There W18 calculates to 0.26807
So
log10 (3939) = 9.36*log10(SN+1) -.2/(.4+1094/(SN+1)5.19)) -6.01
Structural Number SN = a1*d1 + a2*d2 *m2 +a2*d3 *m3
= a1*d1 + a2*d2 +a2*d3
Answer:
h=1.122652m
Explanation:
Assuming density of air = 1.2kg/m³
the differential pressure is given by:
Answer:
Hand tools based on job requirement and its importance and the classification of hand tools according to its function and its importance are discussed below in details.
Explanation:
Hand tools based on work requirement is essential because Every tool is specifically invented for a particular purpose, so picking the accurate tool will also reduce the amount of energy needed to get work done right without causing injury or harm to either the tools or the exterior being worked on.
classifying of hand tools: wrenches, screwdrivers, cutters, striking tools, hammer tool or struck, pliers, vise, clamps, snips, saws, drills, and knives.

Answer:
work done = 665.12 kJ/k.mol of nitrogen
dQ = 685.905 kJ/k.mol of nitrogen
Explanation:
given data
pressure = 80 bar
temperature t1 = 220 K
temperature t2 = 300 K
solution
first we get here work done as considering ideal gas condition
work done = P (v2-v1 ) = nR (t2-t1)
put here value
work done = 1 × 8.314 ×( 300 - 220 )
work done = 665.12 kJ/k.mol of nitrogen
and
now we get heat transfer by 1st law of thermodynamics that is
heat transfer dQ = dv + dw
dQ = Cv dT + dw
put here value and we get
dQ = 
× (t2-t1) + 665.12
dQ = 
× (300-220) + 665.12
dQ = 685.905 kJ/k.mol of nitrogen
