Metamorphism grades into what at the high-grade end? ... Calculate the equilibrium curve for the reaction calcite + quartz = wollastonite + CO2. This problem is similar to the example problem in this chapter, with the addition of the gas pressure terms in Equation (27.8). The pertinent thermodynamic data are listed in the table below.

In this case, the formula above would define y, the elevation at any point along the curve, by starting at A, extending the initial slope g1 to a point directly under point P on the curve, and then determining the vertical distance from the extended gradient to that point on the curve.

Note: The offsets between vertical curve and the grade lines are symmetrical about the point where the gradients intersect. Examples of calculations of vertical curves are shown on drawing 304-A3-83-335. A vertical curve is not necessary where a + b is less than 0.2.

Note: The vertical curve is symmetrical about the point where the gradients intersect. Examples of calculations of vertical curves are shown on drawing 304-A3-83-335. A vertical curve is not necessary where a + b is less than 0.2. Otherwise vertical curves should not be less than 20m in length and should be rounded up to the next multiple of 20m.

Lecture 5 - Calculate the length of vertical curve to obtain sight distance. Calculation of the length of VC is based on the offset part of the equation for a parabolic curve and the use of standard offset heights. For the metric case the offsets are 1.08 m and 0.6 m for eye height and object height respectively. The equations are developed below

Example 4: With a two-lane sag vertical curve with entering and exiting tangent grades of -2.50% and +4.00% respectively and a design speed of 100 km/h, calculate the minimum vertical curve length. From Table 5 with a 100 km/h design speed, the required stopping sight distance is 185 meters and the rate of vertical curvature is 45.
