agasfer [191]

Answer:

408 J/kg

662696.7 J/kg

Explanation:

Workdone by compression process in a pump can be isothermally expressed as :

W = P_1V_1 \ In \frac{P_2}{P_1}

For water at inlet pressure 1. 0 bar;

the specific values for :

saturated vapor v_g = 1.694 m^2 kg

saturated liquid v_f = 0.001043 \  m^2 kg

∴ we have

P_1 = 1.0 bar = 1. 0 × 10⁵ N/m²

P_2 = 50 bar = 50  × 10⁵ N/m²

For saturated water output from condenser work; we have

W = P_1V_f \ In (\frac{P_2}{P_1})

W = (1.0*10^{-5})(0.001043) In ( \frac{50}{10} ) J/kg

W = 408 J/kg

For saturated vapor output from condenser

Work required :

W = P_1V_g \ In ( \frac{P_2}{P_1} )

W = 1.0*10^5*1.694 \ In ( \frac{50}{1.0}) J/kg

W = 662696.7 J/kg

In a river reach, the rate of inflow at any time is 350 cfs and the rate of outflow is 285 cfs. After 90 min, the inflow and out
Semenov [28]

Answer:

change in storage =  -310,500 ft^3

intital storage= 3.67 acre ft

Explanation:

Given data:

Rate of inflow = 350 cfs

Rate of outflow = 285 cfs

After 90 min,  rate of inflow = 250 cfs

Rate of outflow = 200 cfs

final storage = 10.8 acre-ft

calculating the average inflow and outflow

average inflow  = \frac{(350+250)}{2} = 300 cfs

average outlow  = \frac{(285+200)}{2} = 242.5 cfs

total amount of water drain during the period of one hour

= (average outflow - average inflow) *60*90

= (242.5 - 300)*60*90 = -310,500

change in storage is calculate as

= -310,500 ft^3

in cubic meter

= -310500/35.315 = 8792.30 cm^3

in acre-ft

= -310,500/43560 = 7.13 acre ft

initial storage = 10.8 - 7.13 = 3.67 acre ft

You were recently hired by the Andrews CEO as a consultant to evaluate the performance of the Chief Financial Officer (CFO). As
goldfiish [28.3K]

Answer: Collect more information about the extent to which this reported behavior is impacting others

Explanation:

The options are:

a. Collect more information about the extent to which this reported behavior is impacting others.

b. Tell the CEO about what you have uncovered and ask for her permission to speak about it with the CFO.

c. Focus on the CFO’s work performance since his personal behavior is inappropriate in the workplace.

d. Inform the human resources department that there is a potential problem.

Given the information provided in the question, the most effective next step in the process will be to collect more information about the extent to which this reported behavior is impacting others. This will be vital in determining whether what is being said about the Chief Financial Officer is true or not and also to know if true, whether it has an affect on the performance of affected employees in the organization.

Option B is wrong as telling the CEO right away isn't the next step as adequate information must be gathered first.

Option C is also wrong as the focus shouldn't be on his work in the organization alone. His personal behavior should be addressed as well if he's wrong. A great organization is made up of great individuals with good behaviors.

Option D is also wrong as the next step should not be to inform the human resource.

Therefore, the correct option is A.
