B1. Consider a hypothetical material that has a grain diameter of 2.0x102 mm. After a heat treatment at 550°C for 4 h, the grain diameter has increased to 8.0 x102 mm. Compute the time required for a specimen of this same original material (do = 2.0x10 mm) to achieve a grain diameter of 5.5x10² at 550°C. Assume the n (grain diameter exponent) has a value of 2.2

Chemistry A disk type centrifuge with disks at 450 angle is used to clarify a suspension of E.coli cells with sedimentation velocity of 5.5x10-5 cm/s. Determine the number of disks required to get the output flow of 200 liters/min if the speed is 6250 rpm and RO = 12.7 cm and R1 = 4 cm.
A capillary viscometer was used to measure the viscosity of a fluid at room temperature. At a pressure drop per unit length of 0.28 mmHg cm−1, i.e., ΔP/L, the measured flow rate of the fluid through the capillary viscometer was found to be 0.0125 cm3 s−1. When the value of ΔP/L was increased to 0.79 mmHg cm−1, the flow rate of the fluid was found to be .047 cm3 s−1. Under these conditions, is the fluid Newtonian or non-Newtonian? Be sure to justify your answer.
Aluminum atoms are to be diffused into a silicon wafer using both predeposition and drive-in heat treatments; the background concentration of Al in this silicon material is known to be 2.5 x 101⁹ atoms/m³. The drive-in diffusion treatment is to be carried out at 1050°C for a period of 4.0 h, which gives a junction depth x; of 3.0 μm. Compute the predeposition diffusion time at 950°C if the surface concentration is maintained at a constant level of 2 x 1025 atoms/m³. For the diffusion of Al in Si, values of Qd and Do are 3.41 eV and 1.38 x 10-4 m²/s, respectively. min
