The typical thermodynamic efficiency of an OTEC installation running between surface water at 22 C and deep water at 14 C is about?
(1 - (287/295)) *100 = 2.711% efficiency.
273+14C = 287K
273+ 22C = 295K
On Earth, it's more like 25C surface and 10C deep, ish, depending on where you are. In absolute (Kelvin) temperatures, that's 298K and 283K
The Carnot efficiency (maximum possible efficiency) of this is
1 - 283 / 298 = 5%
I met a guy years ago who reckoned he could get 3% real efficiency from his OTEC design.
OTEC will always have extremely low efficiency. It relies for its success on the heat being free (it is) and on being able to shift vast amounts of ocean water around with minimal friction losses (that's a bit harder).
What else can I help you with?
How do you calculate efficiency in ring frame?
Efficiency in a ring frame can be calculated by dividing the total output (in hanks or meters) by the total machine running time and multiplying by 100. Formula: Efficiency = (Total output / Total machine running time) * 100. This measure helps assess the productivity and performance of the ring frame in converting raw material into finished products.
Does friction reduce efficiency of a machine?
When a machine is running at 100 % efficiency there is no loss of energy anywhere. That means the machine is running silently and if turned off will continue to run without stopping. In the real world there is sound and there is friction. Both sound and friction are examples of less than perfect efficiency
What is the normal gauge pressure on the suction line of a running refrigerator?
The normal gauge pressure on the suction line of a running refrigerator is typically between 0 to 5 psi. It can vary depending on factors such as the type of refrigerant being used, the operating conditions, and the age and efficiency of the refrigerator system. It is important to refer to the manufacturer's specifications for the specific pressure range for your refrigerator.
Does the way you run affect your speed?
Yes, the way you run can affect your speed. Proper running form, posture, stride length, and arm movement can all contribute to improved speed and efficiency. Working on your running technique through practice and feedback can help you become a faster runner.
Why is it important to understand the relationship between time, distance, and speed?
Understanding the relationship between time, distance, and speed is important because it helps us calculate how long it will take to travel a certain distance at a given speed, or how far we can go in a specific amount of time. This knowledge is crucial for planning and executing various activities, such as driving, running, or even scheduling events. It also helps in making informed decisions about efficiency and safety in different situations.
The typical thermodynamic efficiency of an OTEC installation running between surface water at 220 C and deep water at 40 C is about?
40C + 273 = 313K 220C + 273 = 493K (1 - (313/493)) *100) = 36.5% thermodynamic efficiency. Amazing, but then your temperatures are fantastic!
The typical thermodynamic efficiency of an OTEC installation running between surface water at 22 C and deep water at 40 C is about?
Deep water is cooler. YOUR NUMBER ARE WRONG
What is the difference between cadence and speed in terms of running efficiency and performance?
Cadence refers to the number of steps a runner takes per minute, while speed is how fast a runner covers a distance. A higher cadence is generally associated with better running efficiency and reduced risk of injury, while speed is a measure of how quickly a runner can complete a race. Increasing cadence can improve running efficiency and performance, while focusing solely on speed may lead to decreased efficiency and increased risk of injury.
Do running shoes have a big impact on running?
The right running shoes can improve your running efficiency and help you reach your goals more easily, especially when competing.
You are trying to install sktpe but you get an error message Installing Skype failed code 1618Another installation is already progress Complete that installation before proceeding with this installati?
This means there is an installation running in the background, it could be a windows update still installing, something you got for your computer that's still installing or it could be anything else still installing. If you can't find the installation that's running try checking the Task Manager for running installation processes or if that doesn't work try restarting your computer. Hope this helps.
Can Low Running Harm Diesel Engines?
nothing like that , but people which have low running go for petrol because , the price difference between them more than one lack . in the case of diesel engine it get good milage and efficiency at optimum temperature this can achieved only by good running.
How much space is needed between floors for installation of plumbing for a new bathroom?
You can do it with about 300 mm but you have to keep in mind what direction you are running the floor joists in. That way you will have to drill fewer holes in them.
How does the process of running alcohol affect the efficiency of a distillation system?
The process of running alcohol can affect the efficiency of a distillation system by impacting the separation of alcohol from other components. Higher alcohol content in the initial mixture can lead to faster distillation and higher efficiency, while impurities or lower alcohol content can slow down the process and reduce efficiency.
How can electricity be conserved?
By not wasting t. By using it optimally, By running the equipment with highest efficiency
What is the optimal sprinting cadence for maximizing speed and efficiency in running?
The optimal sprinting cadence for maximizing speed and efficiency in running is generally considered to be around 180 steps per minute. This cadence helps to improve running economy and reduce the risk of injury by promoting a more efficient stride and faster turnover.
What is difference between erroction and commissioning?
Installation of a system or machinery up to the point of being able to start running is erection. Commissioning is preparing for running or taking into use of the installed system or machinery by making preliminary tests and checks (pre-commissioning) and initially running the system or machinery or taking it into use while checking and setting all of its running parameters in accordance with its design (hot commissioning).
What winnt32 switch is used to prevent dynamic update from running?
The winnt32 switch used to prevent dynamic update from running is /nodup. This switch is used during the Windows installation process to skip the dynamic update feature, which downloads and installs updates during the installation.
