Radioisotopes of indium are used as tracer particles in diagnostic tests to locate areas of infection. indium has a tetragonal unit cell with a= 0.325 nm and c= 0.495 nm. if the atomic packing factor is 0.693 and the atomic radius is 0.1625 nm, determine the number of atoms in each unit cell

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

Aflywheel accelerates for 5 seconds at 2 rad/s2 from a speed of 20 rpm. determine the total number of revolutions of the flywheel during the period of its acceleration. a.5.65 b.8.43 c. 723 d.6.86
