He following data on baker’s yeast in a particular medium at 23.4°c were obtained in the presence and in the absence of an inhibitor, sulfanilamide. the reaction rate (–rs) was measured in terms of the oxygen uptake rate (ro2), obtained as a function of oxygen partial pressure. assume the rate ro2, follows michaelis-menten kinetics with respect to oxygen. calculate the ro2 maximum (i. e., vmax), and the michaelis-menten constant km.

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.
