- 7.4 Impeller viscometer The rheology of a Penicillium chrysogenum broth is examined using an impeller viscometer. The density of the cell suspension is approximately 1000 kg m³. Samples of broth are stirred under laminar conditions using a Rushton turbine of diameter 4 cm in a glass beaker of diameter 15 cm. The average shear rate generated by the impeller is greater than the stirrer speed by a factor of about 10.2. When the stirrer shaft is attached to a device for measuring torque and rotational speed, the following results are recorded. Stirrer speed (s¹) Torque (Nm) 0.185 3.57 × 10-6 0.163 3.45 × 10-6 0.126 3.31 x 10-6 0.111 3.20×10-6 Can the rheology be described using a power-law model? If so, evaluate K and n.arrow_forward(read image)arrow_forward(read image) Answer Providedarrow_forward
- This is part B Part A's question and answer was find moment of inertia (Ix = 3.90×10^5) and radius of gyration (kx = 21.861) Determine the centroid ( x & y ) of the I-section, Calculate the moment of inertia of the section about itscentroidal x & y axes. How or why is this result different fromthe result of a previous problem?arrow_forwardDetermine by direct integration the moment of inertia of theshaded area of figure with respect to the y axis shownarrow_forwardConsider the feedback controlled blending system shown below, which is designed to keep theoutlet concentration constant despite potential variations in the stream 1 composition. The density of all streamsis 920 kg/m3. At the nominal steady state, the flow rates of streams 1 and 2 are 950 and 425 kg/min,respectively, the liquid level in the tank is 1.3 m, the incoming mass fractions are x1 = 0.27, x2 = 0.54. Noticethe overflow line, indicating that the liquid level remains constant (i.e. any change in total inlet flow ratetranslates immediately to the same change in the outlet flow rate). You may assume the stream 1 flowrate andthe stream 2 composition are both constant. Use minutes as the time unit throughout this problem. Identify any controlled variable(s) (CVs), manipulated variable(s) (MVs),and disturbance variable(s) (DVs) in this problem. For each, explain how you know that’show it is classified.CVs: ___________, MVs: _____________, DVs: ______________ b) Draw a block diagram…arrow_forward
