Find the equation of the hyperbola with center (4, - 1), transverse axis parallel to the Y-axis, distance between foci 10, latus rectum 9/2.
A study of the compressibility charts, Items B 19 through B 21, will reveal that certain combinations of PR and TR will produce compressibility factors of Z = 1, as if the gas were ideal. (a) List several of these combinations from Item B 20. (b) What will be the state (p psia, t°F) of a given fluid (other than ideal) to produce Z = 1 if that fluid is air? Ammonia? Helium?
A booster station compresses 50 kg/sec of methane from 14 atm, 285 K to 92 atm in a reversible and isothermal steady state steady-flow manner. Use the general ized fugacity coefficient chart (Item B 37) and calculate the compression work and the heat transfer. Now solve using ideal gas theory and compare answers.
What is the Molar concentration of a solution of 10.5 g of glucose (C6H12O6) is dissolved in enough water to make 20.0 mL of solution
Explain set (with 2-set) associative mapping cache. Consider a 4-way set associative mapped cache of size 64 KB with block size 512 bytes. The size of main memory is 256 KB. Find:a) Number of bits in tag b) Tag directory size
The inreversible isomerization

CA(mol/dm3) 4.0 2.89 2.25 1.45 1.0 0.65 0.25 0.07
(a) Use regression to determine the reaction order, a, and the specific reaction rate, ka.
The flat base of the bottom of an electric water heater is made of a 2 mm thick steel plate. thermal conductivity of 40 W/(m. oC), and an insulating plate with a thickness of 4 mm and thermal conductivity of 0.06 W/(m.oC). Between the steel and insulating plates there is an electrical resistance (RE) that dissipates a power of 800 W.
Consider the steady state situation with boiling water at a temperature of 100 oC and with a coefficient of heat transfer by convection of 3000 W/(m2. oC), while the ambient air, which is in contact with the insulator, it remains at a temperature of 25oC and a convection heat transfer coefficient of 10 W/(m2.oC).
Considering a perfect thermal contact between the electrical resistance and the steel and insulating sheets and that the base of the heater has an area of 0.018 m2, determine:
a) The temperature (TR) of the electrical resistance
b) The rate of heat lost to the air through of the insulating plate
ç). The rate of heat lost to water through the steel plate
Consider page reference string of 1 2 3 0 5 0 1 2 1 4 5 0 7 1 2
Using the first in first out (FIFO) page replacement algorithm, draw THREE
(3) page frames (3 pages can be in memory at a time during the process) for the
above-mentioned page reference string. b Calculate the hit rate and fault rate
for your answer.
