A textile finishing process involves drying a fabric that has been treated with a volatile solvent. The wet fabric entering the

dryer contains 45% solvent, and the dried fabric contains 3% of the entering solvent. Solvent-free air enters the dryer at a rate of 8 pounds per pound of solvent-free fabric. The solvent has a molecular weight of 60 g mol-1. (a) Calculate the percentage of solvent in the dried fabric by weight. (Answer: 2.4%) (b) Calculate the concentration of solvent in the dryer exhaust in mg m-3 if the exhaust is at 160 F and 1.0 atm.

Repair calls are handled by one repairman at a photocopy shop. Repair time, including travel time, is exponentially distributed,
wolverine [178]

Answer:

the average number of customers awaiting repairs = 0.30

the system utilization = 42

the amount of time that the repairman is not out on a call is  = 4.64 hours

the probability of two or more customers in the system = 0.1764

Explanation:

Given that :

Repair time, including travel time =  mean of 1.6 hours per call.

Requests for copier repairs = mean rate of 2.1 per eight-hour day

i.e mean rate R = 2.1/day

Time = 8 hours

thus; mean rate μ = 8 hours/ 1.6 hours = 5

(a)

Let the average number of customers awaiting repairs be I_i :

I_i = \dfrac{R^2}{\mu (\mu-R)}

I_i = \dfrac{2.1^2}{5 (5-2.1)}

I_i = \dfrac{4.41}{5 (2.9)}

I_i = \dfrac{4.41}{14.5}

\mathbf{I_i = 0.30}

the average number of customers awaiting repairs = 0.30

(b) Determine system utilization.

The system utilization is determined as follows:

\delta = \dfrac{R}{\mu}

\delta = \dfrac{2.1}{5}

{\delta = 0.42}

\mathbf{\delta = 42}

(c) The amount of time during an eight-hour day that the repairman is not out on a call is calculated as :

Percentage of Idle time = 1 - \delta

Percentage of Idle time = 1 - 0.42

Percentage of Idle time = 0.58

However during an 8 hour day; The amount of time that the repairman is not out on a call is = 0.58 × 8 = 4.64 hours

(d)

the probability of two or more customers in the system by assuming Poisson Distribution is:

P(N ≥ 2) = 1 - (P₀+ P₁)

where;

P₀ = 0.58

P₁ = 0.58  × 0.42 = 0.2436

P(N ≥ 2) = 1 - ( 0.58 + 0.2436)

P(N ≥ 2) = 1 - 0.8236

P(N ≥ 2) = 0.1764

Thus; the probability of two or more customers in the system is 0.1764

Anita is developing a website for her photography business. On the home page, she wants to include a link to another webpage in
kotegsom [21]

Relative link can be inserted.

A relative link thinks that the page to which you're connected is the website and folder to which you've posted the web page. This link is under the same website URL and folder (Articles) as this page, thus we only refer to it by this link. There are two advantages of using relative references versus absolute references.

A Relative Reference is a partial http address that is a portion of a whole directory path. Remember that if no server name or path is supplied in html, the file reference will default to the current directory.

Therefore the answer is relative link.
