5 kg of butane (C4H10), contained in a piston-cylinder device undergoes a process from P1 = 5 MPa, T1 = 500 K to P2 = 3 MPa and T2 = 450 K during which the relationship between pressure and specific volume is PVn = C.
a. Using the data from Generalized Compressibility chart, determine the amount of work done during the process.

b. If butane is assumed an ideal gas, how would you compare the work done during the process to the one that you have obtained above.
QUESTION 9 (PO2, CO2, C6)
For a system that contains butane as described in the above question (QUESTION 8), by making appropriate assumptions, investigate and discuss the effect of polytopic exponent on work boundary and heat transfer, for the system to reach the same:
a. final volume. b. final pressure ( 25 marks )

PLEASE ANSWER QUESTION 9 ACCORDING TO GIVEN MARKS

The following data represents the number of children born in individual pregnancies in 1996 and 2006:

# of children 1996 frequency 2006 frequency
one child 3671455 3971276
twins 100750 137085
triplets 5298 6118
quadruplets 560 355
quintuplets or more 81

A. Define the random variable x= number of children born in a single pregnancy in 1996 and develop a probablity distribution for the random variable. let x=5 represent quintuplets or more

B. Compute expected value and variance for the number of children born in a single pregnancy in 1996

C. define a random variable = number of children born in a single pregnancy in 2006 and develop a probability distribution for the random variable. let y = 5 represent quintuplets or more

You have n numbers and you want to find a number x (out of the n) such that x is larger than the median. You can create an algorithim that takes time O(nlogn): sort the n numbers and then report any number that is larger than the element in position n2 of the sorted array. You can also create an algo in O(n) time, by finding the median in linear time and then doing a linear scan to find a number larger than the median.

Now I need to design a procedure that solves the same problem in time O(k), where k < n. The procedure will be probabilistic, i.e., it will succeed in finding the number larger than the median with probability that depends on k. FInd this dependency.

The American Housing Survey reported the following data on the number of times that owner-occupied and renter-occupied units had a water supply stoppage lasting 6 or more hours in the past 3 months.

Number of Houses (1000s)
Number of Times Owner Occupied Renter Occupied
0 549 23
1 5,012 542
2 6,100 3,734
3 2,544 8,690
4 times or more 558 3,783

Do not round intermediate calculations. Round your answers to two decimal places.

a. Define a random variable x = number of times that owner-occupied units had a water supply stoppage lasting 6 or more hours in the past 3 months and develop a probability distribution for the random variable. (Let x = 4 represent 4 or more times.)

e. What observations can you make from a comparison of the number of water supply stoppages reported by owner-occupied units versus renter-occupied units?

The number of times of water supply stoppages in owner-occupied houses is Select greater/ less Item 17 than in renter-occupied houses, and the variability in the number of times is Select greater/less Item 18 for the owner-occupied houses

Two pith balls hang side by side close to each other without touching as shown in the figure below. They are both neutral to begin with.

Two pith balls hang side by side close to each other without touching as shown in the figure below. They are both neutral to begin with.

 

  1. A plastic rod is rubbed with wool. Describe as negative, positive or neutral the total (net) charge of a system consisting of the rod and the cloth. Explain your reasoning.

 

  1. A student touches sphere A briefly with the rod and then removes it. What is the charge state of A? Same as the rod or opposite charge of the rod?

 

 

  1. Then he brings the rod close to sphere A but does not touch it. What will happen to A? Explain your reasoning.

 

  1. Now sphere B is brought very close to A but does not touch it. What will happen to the spheres? Explain your reasoning.

1. Compare coenzymes with substrates. Explain how they both collaborate in enzyme catalysis.

2. High levels of ammonia (NH3) are toxic to mammals. One reason is that ammonia bonds with alphaketoglutarate in the citric acid cycle, forming the amino acid glutamate. This removes alphaketoglutarate from the Krebs cycle. Explain what consequences this will have for the cell.

3.  Pyruvate + NADH + H+ à lactate + NAD+

Name the oxidizing agent in the above reaction. Explain

4. Trace the steps of a carbon atom from a starch molecule contained in the Donut you just eat until it ends up in a muscle protein.

Please answer ASAP!!

  1. A wastewater plant with the activated sludge process received 5 × 106 L/day of wastewater with a BOD5 of 500 mg/L. The primary clarifier removes 30% of the BOD and primary clarify effluent has no biomass (Xi=0 mg/L). Recycle (Qr) and waste sludge (Qw) flows are 25% and 2% of Qin, respectively. Effluent BOD5 from secondary clarifier and waste sludge is 20 mg/L. Microorganism concentration in the waste sludge (Xw) is 6,000 mg/L. Soluble BOD5 is biologically converted into CO2 and Y (yield coefficient) is 0.5 mgVSS /mgBOD

In the game of ScrabbleTM, the letters of the English alphabet are inscribed on tiles and a prescribed number of tiles are provided for each letter. Consider an ensemble of ScrabbleTM tiles with a probability distribution defined by the frequency of tiles in the box. Explain how to calculate the information entropy of this ensemble. It is not necessary to actually Compute the entropy, but you can if you wish.
