"An equal-tangent sag vertical curve connects a –1.5% initial grade and a +1.25% final grade. The design speed is 70 mi/h and th
e station and elevation of the PVT are 138+70 and 851.5 ft, respectively. A storm drain is to be installed at the low point of the curve. What is the station and elevation of the low point?"

Answer:
Explanation:
Considering the relation of the equilibrium vacancy concentration ;
nv/N = exp (-ΔHv/KT)
Where T is the temperature at which the vacancy sites are formed
K = Boltzmaan constant
ΔHv = enthalpy of vacancy formation
Rearranging the equation and expressing in term of the temperature and plugging the values given to get the temperature. The detailed steps is as shown in the attached file
