Question

correct format Equipment: hollow cylinder, vernier caliper Procedure: A student was asked to use Vernier caliper to measure the necessary dimensions of hollow cylinder, bullet-shapes object, 3D rectangular wood object to calculate the volume of each object and its error. The Vernier caliper is precise to 0.05 mm, so many of the measurements gave the same results. Each dimension was measured 6 times. The collected data is provided in table below Table Hollow cylinder Thickness, mm 5.10 5.05 4.70 5.00 4.90 5.10 Inner diameter, mm 75.75 76.20 76.00 76.10 76.15 76.10 Height, mm 128.00 127.95 127.90 28.05 128.00 Based on the acquired data, use Logger Pro to find the mean value of each dimension and the standard deviation. Using the above measurements to calculate the standard error (standard deviation of the mean) for each dimension'; the mean value of volume for hollow cylinder and its standard error The final results should be reported in centimeters. using the correct format 2

Explanation / Answer

Volume of hollow cylinder = 3.14 * (Rout2 - Rin2 ) * H

Volume , V1 =   165,680.2028 mm3

Volume , V2 =    164,996.4461 mm3

Volume , V3 =    152,461.9799 mm3

Volume , V4 =    162,933.8335 mm3

Volume , V5 =    159,763.8636 mm3

Volume , V6 =    166,527.5327 mm3

=> mean volume = (V1 + V2 + V3 + V4 + V5 + V6)/6

                              = 162060.6431 mm3

                                     = 162.0606   cm3
