Cooling water available at 10°C is used to condense steam at 30°C in the condenser of a power plant at a rate of 0.60 kg/s by circulating the cooling water through a bank of 7-m-long 1.2-cm-internal-diameter thin copper tubes. Water enters the tubes at a mean velocity of 4 m/s and leaves at a temperature of 24°C. The tubes are nearly isothermal at 30°C. Determine the average heat transfer coefficient between the water, the tubes, and the number of tubes needed to achieve the indicated heat transfer rate in the condenser.

what factors need to be considered when building housing on a waterway

Answers

Answer:

Flooding

Explanation:

.

When building housing on a waterway one must always consider the factor of Flooding and its repercussions.

What is a Flood?

A flood occurs when there is an excessive amount of water and it covers normally dry areas. The word can also refer to the tide's influx when used in the sense of "flowing water." Floods are a topic of research in the hydrology field and are very important to the fields of agriculture, civil engineering, and public health.

Floods have serious societal repercussions for both communities and people. As most people are well aware, flooding has a number of direct effects, including the loss of life, destruction of property, loss of crops and livestock, and worsening of health due to waterborne infections.

Stream gauges that are put in bodies of water close to inhabited areas are used to measure floods. The National Weather Service receives all data collected by them before it is sent to the United States Geological Survey (USGS), which erected and operates them (NWS)

The form of energy delivered to an electrical generating turbine in a geothermal facility is in the form of ________.

Answers

Geothermal energy is a product of the heat of Earth's molten interior. The form of energy delivered to an electrical generating turbine in a geothermal facility is in the form of hot water or steam.

Geothermal energy is gotten so as to generate electricity. This is done when water is injected deep underground and it then comes back as steam or hot water.

This is then converted to steam so as to drive a turbine on an electric power generator. The plants makes use of steam to produce electricity.

There are three main types of energy for electricity generation. They are fossil fuels which is made up of coal, natural gas, and petroleum, and then nuclear energy, and renewable energy sources.

State three means of operating a power tool

Answers

Answer:

A power tool is a tool that is actuated by an additional power source and mechanism other than the solely manual labor used with hand tools. The most common types of power tools use electric motors. Internal combustion engines and compressed air are also commonly used. Other power sources include steam engines, direct burning of fuels and propellants, such as in powder-actuated tools, or even natural power sources such as wind or moving water. Tools directly driven by animal power are not generally considered power tools.

Power tools are used in industry, in construction, in the garden, for housework tasks such as cooking, cleaning, and around the house for purposes of driving (fasteners), drilling, cutting, shaping, sanding, grinding, routing, polishing, painting, heating and more.

Power tools are classified as either stationary or portable, where portable means hand-held. Portable power tools have obvious advantages in mobility. Stationary power tools, however, often have advantages in speed and precision. A typical table saw, for instance, not only cuts faster than a regular hand saw, but the cuts are smoother, straighter, and more square than what is normally achievable with a hand-held power saw. Some stationary power tools can produce objects that cannot be made in any other way. Lathes, for example, produce truly round objects.

Stationary power tools for metalworking are usually called machine tools. The term machine tool is not usually applied to stationary power tools for woodworking, although such usage is occasionally heard, and in some cases, such as drill presses and bench grinders, exactly the same tool is used for both woodworking and metalworking.

Concrete has a higher specific heat than does soil. Use this fact to explain (partially) why a city has a higher average temperature than the surrounding countryside.

Answers

Answer:

Since concrete has higher specific heat, it will absorb more heat and the temperatures will rise in proportion. The large amount of energy stored in concrete during the day as the sun falls on it is released at night, resulting in an higher average evening temperature than the countryside. The cool air in the surrounding countryside exerts a buoyant force on the warmer air in the city, pushing it upward and moving into the city in the process. Thus, evening breezes tend to blow from country to city.

Explanation:

The city has a higher average temperature than the surrounding countryside as most of the cities are made up of concrete designs one of the things which absorb a lot of heat.

What is soil?

Soil contains lots of minerals as well as microorganisms. One can grow crops or vegetation on the soil. This is made up of various types of sand and granules that can be present.

Concrete absorbs more heat because of its high surface heat, which causes temperatures to rise proportionately. Asphalt absorbs a lot of energy generated by the sun each day and releases it at night, giving cities a warmer average nighttime weather than rural.

The heated air in the city is propelled higher and toward the city by the density of water of the cooler in the nearby countryside. As a result, evening gusts frequently travel between rural to city.
