Hi! Help me with this please. Thank you so much! A dumpy level is set up at one end of a line 160m. long for the purpose of determining the instrument stadia interval factor. The line is marked by hubs at every 40 m. and a stadia rod is held at each hub. The stadia intercept at each location of the rod were observed as follows: 0.402, 0.813, 1.231, 1.602 respectively. Compute the average value of the stadia interval factor. Height of instrument is 1.5m.

The following data were taken along a center line of a dam AB. The staff had been held in the 1st case at a starting point (A) and then at 20m intervals. The staff readings were: 0.765 / 1.064/ [0.616] / 1.835 / 1.524. The level was then moved forward to another position and further readings were taken as follows: 2.356 / 1.378 / [2.063] / 0.677/ 2.027. The last reading was at point (B). The R.L of (A) is 41.819m. 1- Enter the above data in a level book form. 2- Find the reduced level of points using height of collimation method. 3- Check the results. 4- Calculate the gradient from A to B. Note: readings in brackets are inverted staff readings.
