Problems 1-4: For a globular protein of diameter 6 nm, corresponding to a molecular mass of 100 kDa, 1. Calculate the mass in kg. 2. Calculate drag coefficient assuming η_1mPa's 3. Calculate viscous force at 25°C given: The average instantaneous thermal speed of a protein v-(3k*T/m)0.5 k is Boltzmann constant, 1.381 x 10-23 J/HK Tis the absolute temperature, 0 K-273.15°C 1J 1 N'm. 4. Calculate the speed of the protein caused by the centrifugal force. Assume that the centrifugal force...
summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
A 3 m rigid bar AB is supported with a vertical translational spring at A and a pin at B The bar is subjected to a linearly varying distributed load with maximum intensity g Calculate the vertical deformation of the spring if the spring constant is 700 kN/m. (ans: 21.43 mm) 2. A steel cable with a nominal diameter of 25 mm is used in a construction yard to lift a bridge section weighing 38 kN. The cable has an...
summatize the following info and break them into differeng key points. write them in yojr own words apartus 6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
