Ty] Calculate the settling velocity of the following spherical objects. The surrounding medium property can be taken as water (viscosity = 0.001 Pa-s, density =1000 kg/m3 ). (a) A yeast cell (Saccharomyces cerevisiae). Diameter= 6 microns,  =1.1 g/cm3 (b) A spherical steel particle. d= 6 microns, density = 8 g/cm3 (c) A spherical steel particle. d = 6 mm, density = 8 g/cm

Agas contained in a piston-oylinder assembly is initially at p1=100 ibf/ft^2? and occupies a volume of 3.75 ft. the gas is compressed to a pressure p2=500 ibf/ft^2 and a final volume of 0.5 ft. during the process, the relationship between pressure and volume is given as p= a +bv, where a and b are constants a)-determine the values and units for a and b b)-determine the volume, in ft, at an intermediate state where the pressure is 300 ibt/t2.
