if the areas of the two sides of a prismoid represent 211.76m² and 134.67m², which are 6m distance apart , find the total volume using trapezoidal formula

The streamline passing through the distance '8' from the surface at the trailing edge passes through distance 'y' at the leading edge as y shown in figure below. The ratio is (Assume linear profile inside the boundary layer). Streamline U y 10

Can you please provide the solution on solving the centroid answers are provided. 1. Centroid from the base : 49.78 2. Centroid from the left side: 77.73

A line is regarded as 485 m long. It is measured with a 500 grams tape which is 30.05 m long at 20°C under a 4.5 kg pull supported throughout its length. During measurement the temperature is 4.5°C and the tape is suspended under a 6.5 Kg pull. The line is measured at 3% grade. What is the true horizontal distance? ◦E=2x106 kg/cm2 ◦v =126.54 cm3/kg Given:   Nominal Tape Length L1 Total weight of tape W Standard Temperature of Tape T1 Temperature during measurement T2 Standard Pull of Tape P1 Pull applied during measurement P2 Measured Distance Di correction due incorrect tape length Ci Ground slope S Cross-sectional area of the tape A   Solution correction per tape length (correction per 30-m length) incorrect tape length CI Question Blank 11 of 20 meter temperature correction CT Question Blank 12 of 20 meter pull correction CP Question Blank 13 of 20 meter sag correction CS Question Blank 14 of 20 meter slope correction (approximate method) CSL…
