Geometrical standards for Runways (Transportation Engineering)

Geometric standards for runways Geometric standards for various runways elements are as follow; 1.   length 2.   width 3.   longitudinal gradient & profile 4.   transverse gradient 5.   runway intersections 1) length Selection of length of a runway is the most important decision in the planning of landing area. Runway lengths for various types of airports recommended by ICAO are for sea level elevation, standard atmospheric conditions; ·         59 0 F or 15 0 C ·         29.92”barometer pressure ·         zero effective gradient ·         No wind The basic lengths recommended by FAA are based on the same conditions except that temperature of 100 0 F (41 0 C above standard) has been included in the length. Necessary corrections have to be applied for changes in elevation, temperature a...

To measure the pH of different samples in the laboratory.

Ø Experiment 1                                    To measure the pH of different samples in the laboratory. Ø Theory                                 The pH scale is a measure of the hydrogen ion concentration. The pH scale ranges from 0 to 14. pH symbol rooted in the French " p ouvoir h ydrogene " (power of hydrogen).It measures the acidity or basicity of a solution. A pH of 7 means it is a neutral solution. Pure water has a pH of 7. A pH of less than 7 means the solution is acidic. A pH of more than 7 means the solution is basic. The less pH, the more acidic the solution is. The more pH, the more basic the solution is. pH stands for the power of H, or the amount of...
