Answer:
Tc = = 424.85 K
Explanation:
Data given:
D = 60 mm = 0.06 m
k = 50 w/m . k
c = 500 j/kg.k
HEAT FLOW Q is
= 47123.88 w per unit length of rod
volumetric heat rate
= 424.85 K
The energy in which wind is used to generate electricity is known as wind energy. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power is then used for various purposes. Wind energy is a free and renewable resource. It is a clean and non-polluting source of energy.
Answer:
For detailed answer of "
In subsea oil and natural gas production, hydrocarbon fluids may leave the reservoir with a temperature of 70°C and flow in subsea surrounding of S°C. As a result of the temperature difference between the reservoir and the subsea surrounding, the knowledge of heat transfer is critical to prevent gas hydrate and wax deposition blockages. Consider a subsea pipeline with inner diameter of O.S m and wall thickness of 8 mm is used for transporting liquid hydrocarbon at an average temperature of 70°C, and the average convection heat transfer coefficient on the inner pipeline surface is estimated to be 2SO W/m2.K. The subsea surrounding has a temperature of soc and the average convection heat transfer coefficient on the outer pipeline surface is estimated to be ISO W /m2 .K. If the pipeline is made of material with thermal conductivity of 60 W/m.K, by using the heat conduction equation (a) obtain the temperature variation in the pipeline wall, (b) determine the inner surface temperature of the pipeline wall, (c) obtain the mathematical expression for the rate of heat loss from the liquid hydrocarbon in the pipeline, and (d) determine the heat flux through the outer pipeline surface."

Explanation:
Answer:
The correct option is;
B) Counterproductive
Explanation:
An effective requires adequate preparations, with agenda of the meeting circulated among participants. The items to be discussed should be known before hand by the participants all of whom will have had adequate background information and relevant consultations with their constituencies so as to be able to add effectively to the meeting.
Other attributes of an effective meeting includes;
1. Ensure, notes of the meeting are taken down personally
2. Outside discussions should be made at the parking lot
3. Important decisions or points to be made should have been communicated to other members of the meeting
4. Members to attend the meeting should be well known and list of attendees reviewed
5. Meetings should be kept to schedule
6. Ensure meeting conclusions and decisions are followed up
7. Written agenda should be available
Therefore "winging it" with minimal planning is considered counterproductive.
Answer:
The pressure in the tank is 70.183 k Pa
The volume of the tank is 4.73 m³
Explanation:
Volume of the liquid phase
v(f) = m(f).v(f)
= 8 kg . 0.001036 m³/kg
= 0.008288 m³
Volume of the vapor phase
v(g) = m(g).v(g)
=2 kg . 2.3593 m³/kg
= 4.7186 m³
Volume of the tank = Volume of the liquid phase + Volume of the vapor phase
Volume of the tank
= 0.008288 m³ + 4.7186 m³ = 4.73 m³
