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

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
