A75 kg person doing light work requires about 3000kcal of food energy per day.40% of which is actually use by the body's cells( the other 60% is lost as heat and in waste products) before being used by the cells, effectively all this energy is stored in atp , which is then cleaved into adp and p032-, with the release of 12.5 kcal per mole 0f atp a) how many moles of atp are turned over per day in this fashion? what mass of atp does this correspontd to? ( the molecular weight of atp is 507 g/mol) b) the body actually contais approximately 5g atp. estimate the average recycle time for an atp molecule. you see that it is much more efficient to reuse adp rather than to synthesize it de novo( from scratch)

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa.s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
