fish have proteins  known as walleye Pollock, this white fish is packed with protein. Three ounces (85 grams) contain 20 grams of protein and about 100 calories (21). Alaskan Pollock is an excellent source of omega-3 fatty acids. It also contains large amounts of choline and vitamin B12, as well as many other nutrients.

6. Is inertia the reason for moving objects maintaining motion or the name given to this property?
marshall27 [118]
Inertia is the name. Inertia is when a moving object stays in motion unless stopped by an outside force. This is Newton’s first law of motion

Water enters the turbine of an ideal Rankine cycle as a superheated vapor at 18 MPa and 550°C. If the condenser pressure is 9 kP
ivolga24 [154]

Answer:

For this ideal Rankine cycle:

A) The rate of heat addition into the cycle Qh is 3214.59KJ/Kg.

B) The thermal efficiency of the system εt=0.4354.

C) The rate of heat rejection from the cycle Qc is 1833.32KJ/Kg.

D) The back work ratio is 0.013

Explanation:

To solve the ideal Rankine cycle we have to determinate the thermodynamic information of each point of the cycle. We will use a water thermodynamic properties table. In an ideal Rankine cycle, the process in the turbine and the pump must be isentropic. Therefore S₃=S₄ and S₁=S₂.

We will start with the point 3:

P₃=18000KPa  T₃=550ºc ⇒ h₃=3416.12 KJ/Kg  S₃=6.40690 KJ/Kg

Point 4:

P₄=9KPa S₄=S₃ ⇒ h₄=2016.60 (x₄=0.7645 is wet steam)

Point 1:

P₁=P₄ in the endpoint of the steam curve. ⇒ h₁= 193.28KJ/Kg  S₁=0.62235KJ/Kg  x₁=0

Point 2:

P₂=P₃ and S₂=S₁ ⇒ h₂=201.53KJ/Kg

With this information we can obtain the heat rates, the turbine, and the pump work:

Q_h=Q_{2-3}=h_3-h_2=3214.59KJ/Kg

Q_c=Q_{4-1}=h_4-h_1=1833.32KJ/Kg

W_{turb}=W_{3-4}=h_3-h_4=1399.52KJ/Kg

W_{pump}=W_{1-2}=h_2-h_1=18.25KJ/Kg

We can answer the questions with this data:

A) Q_h=Q_{2-3}=h_3-h_2=3214.59KJ/Kg

B) \epsilon_{ther}=\displaystyle\frac{W_{turb}}{Q_h}=0.4354

C)Q_c=Q_{4-1}=h_4-h_1=1833.32KJ/Kg

D) r_{bW}=\displaystyle\frac{W_{pump}}{W_{turb}}=0.013

1. You are driving south on the 405. You are in traffic so your speed is 35 miles per hour,
Step2247 [10]

Answer:

1. 15.64 m/s

2. 2,354,400 seconds

Explanation:

1. 1mile is equivalent to 1609metres and 1hour is equivalent to 3600sec.

35mph = (35×1609)/3600

= 56315/3600

= 15.64 m/s

2. Note that 1 day ===> 24hrs

60min ==> 1hr

60sec ===> 1min

Thus 27.25 days = 27.25×24×60×60

= 2,354,400 seconds
