Autoregulation of glomerular filtration by tubuloglomerular feedback helps protect thekidney:a. from rapid systemic arterial pressure variations that would otherwise cause largeglomerular filtration rate changes.b. from rapid systemic venous pressure variations that would otherwise cause largeglomerular filtration rate changes.c. by contracting the walls of the efferent arterioles, thus increasing systemic bloodpressure.d. by relaxing the walls of the efferent arterioles, thus reducing systemic bloodpressure.

8) What is needed to evaluate the thermodynamic properties of a saturated mixture that is not completely vapor, and not completely liquid? 9) How many inputs are needed to operate the compressed liquid water tables? Why is this the case? What if the pressure we are interested in is less than the minimum pressure provided in the compressed liquid tables? What is to be done in this case? 10) Discuss the relative dependencies of internal energy on temperature and pressure for superheated vapor and supercooled liquid systems. Relate your discussion to why the compressed liquid water tables start at 25 bar.

Troe Corp manufactures a product that passes through two departments. Data for a recent month for the first department are: Beginning WIP contains 130,000 units with cost of direct material being $89,500, conversion cost of $139,200. Material was 80% complete, Labor and OH was 60% complete. The number of units started in the process is 819,000, units transferred out are 903,000 and WIP ending inventory is 46,000 units (material is 36% complete and conversion is 53% complete). The WIP ending inventory is 36% complete with respect to direct material and .53 with respect to conversion. Cost added during the month for material is $1,036,222, and $1,274,240 for conversion Calculate (using the weighted average method and then the FIFO method) the equivalent units of production regarding direct materials, and conversion. Secondly, calculate the cost per equivalent unit for direct materials, and conversion Weighted Average FIFO
