Answer 1

A hydraulic oil cooler, for instance, will remove heat from heated oil by utilizing cold water or air. A heat exchanger is a device that transfers heat from one medium to another.

Instead, a swimming pool The pool water is heated using a heat exchanger using hot water from a boiler or solar heated water circuit. Heat is transferred from one medium to another using heat exchangers. These media could be a gas, a liquid, or a mix of the two. The media may be in direct contact or separated from one another by a solid wall to prevent mixing. One typical illustration of a heat exchanger is the radiator in a car, where hot water used for engine cooling transmits heat to air passing through the radiator.

A healthcare provider chedule 30 minute for each
patient’ viit, but ome viit require extra time. The random
variable i the number of patient treated in an eight-hour day

Answers

Each patient's visit is scheduled for half an hour by the healthcare professional. Therefore, a maximum of 8x2=16 patients can be treated during an eight-hour shift.

A doctor sets 30 minutes for each patient, but they may need longer time, and he can see them, whereas for the amount of patients you can see in an eight-hour day, we are effectively urged to figure out the range of the random variable in this question. Thus, eight hours are equivalent to 480 minutes.

Therefore, the most patients he can see is if each appointment is only for 30 minutes. That makes it 16, and from there, he only sees one patient up to a maximum of 16. Therefore, it can take up to eight hours for just one patient. I could also see as many as 16 patients, each for exactly 30 minutes.

A process generates 250 watts of useful energy and 600 watts of waste energy. What is the efficiency of the process?.

Answers

A process generates 250 watts of useful energy and 600 watts of waste energy, the efficiency of the process is 29%.

What is energy efficiency?

To perform a task or achieve a goal while using less energy is known as energy efficiency. Energy-efficient homes, buildings, manufacturing facilities, and electronics use less energy to produce goods and less energy to heat, cool, and operate appliances and electronics.

One of the simplest and most affordable strategies for halting climate change, lowering consumer energy costs, and boosting the competitiveness of American companies is energy efficiency. Achieving net-zero carbon dioxide emissions through decarbonization depends on energy efficiency as well.

The Office of Energy Efficiency and Renewable Energy (EERE) supports clean energy through its technical offices and programs that support research and development and encourage energy efficiency in all facets of the American economy.

Energy efficiency = useful energy output/energy input × 100%

useful energy output = 250 watts

energy input = useful energy output  + waste energy ouputs

                      = 250 + 600

                       = 850 watts

Energy efficiency = (250 /850) × 100%

                              = 29%

Is parallelogram ABCD a rectangle?

Answers

Because ABCD is a parallelogram with a single right angle, it is a rectangle.

What kind of parallelogram is ABCD?

Rhombus: If all of a parallelogram's sides are equal or congruent, it is a rhombus. One parallel side and two non-parallel sides make up the shape of a trapezium. In the figure above, you can see that ABCD is a parallelogram where AB || CD and AD || BC.

Why don't all parallelograms have rectangular shapes?

Rectangles and parallelograms both have equal and parallel opposite sides. The angles of a rectangle, however, are all right angles. Consequently, a parallelogram is a specific type of rectangle. As a result, while not all rectangles are parallelograms, all parallelograms are rectangles.

What are three roadway conditions commonly found in rural driving?

Answers

The three roadway conditions commonly found in rural driving are narrow multilane roads, gravel roadways, and rough conditioned roads.

What are three roadway conditions commonly found in rural driving?Narrow roads: One vehicle wrecks and multiple-vehicle collisions are both possible outcomes of an accident on a narrow road. Poor vision, which makes it more difficult to see incoming vehicles, is one of the risks associated with driving on a small road.On curvy roadways, high shrubs and blinds leave a small reactionary window. Maintaining the speed limits is the simplest technique to keep your vehicle safe to drive.Gravel roads: They are challenging to drive on in rainy weather because they are prone to rutting, potholes, wash boarding, and water absorption.Rough roads: Running on rough roads can harm the tires, undercarriage, body, etc. Your repair expense could go from hundreds to thousands of dollars depending on your driving style in certain circumstances.It may even be lethal in the worst-case scenarios of driving in these roadway conditions.
