2 What is the height above sea level at which an aircraft must fly in order to procure photography at an average scale of 1:12 000, if the average elevation of the area is 3000 m and the camera to be used has a focal length of 153 mm? The length of a section line (1 mile) lying at an elevation of about 300 m scales 10.16 cm on a photo. The focal length of the carnera used is 153.26...
1. An exposure station is 1700 m above sea level. The elevation of Point A as seen in the photo is 200 m, and the elevation of Point B as seen in the photo is 720 m. The focal length of the camera is 153 mm. Determine the scale of the photo for the terrain lying at these two elevations.
Images a and b of ground points A and B appear on a vertical photograph taken froma flying height of 2625 m above datum. A 153.16-mm-focal-length camera was used. Points A and B have elevations of 407 m and 311 m above datum, respectively. Measured photo coordinates of the images are xa--60.2 mm, ya 47.3 mm, xb- 52.4 mm, yb 80.8 mm. Calculate the horizontal lengths of line AB. (a) If a third point C was measured with elevation of...
Consider a height 170 m above the ground (which itself is 1247 m above sea level). If the temperature at this height is 10 C, what is the ratio of the density of this site compared to standard atmospheric conditions (hint - assume you can use the ideal gas law to calculate the density and then divide this value by the standard density value)? (answer to three decimal places)
At what height above sea level is the molecular density of air (at 22 degrees celsius) reduced by a factor of 2? assume the average molar mass of air is 29g/mol.
Question 6 (5 Marks) The atmosphere from sea level to 11 km height is a constant lapse rate layer. Assuming a lapse rate of 0.0065°K/m. Calculate the temperature and pressure at a height of 7000 m, given sea level conditions of po=101325 N/m2 and To=15°C. Question 7 (5 Marks) A smooth plastic, 10-m-long garden hose with an inside diameter of 20 mm is used to drain a wading pool as is shown in Figure Q7. Calculate the flowrate from the...
(a) In Masirah Island at a sea-level, the wind statistics, taken over a period of one year and measured at an anemometer height of 10 m above sea-level, are as shown in Figure Q2(a) The velocity is assumed to be constant in each indicated range. Although the wind velocity varies with the 1/7th power of height. The windmill characteristics are: Efficiency 70%, Cost 47.8mT USD/m2, and Weight 10 g/m2. If h is the height of the tower and m is...
Groundwater
Let us assume that the water table on the island is 2 m above sea level. Then, t 2 m, so 2 m/0.03-h 66.67 m. Thus we can predict that if we drill a hole on the island we would not come to salty groundwater for approximately 67+ 2 meters, or about 69 m from the top of the water table. This would be 67 m below sea level. a] Suppose you found a place on the island where...
