What environmental factors increased the rate of transpiration?
Heat and wind.
How At high temperatures the rate of enzyme action decreases because the increased heat?
alters the active site of the enzyme
How water flow rate affect performance of vapour compression cycle?
An increase in water flow rate can improve the performance of a vapor compression cycle by enhancing heat transfer in the condenser and evaporator. This results in better cooling capacity and efficiency of the cycle. However, excessive water flow rates can lead to increased pumping power requirements and higher operating costs.
What is heat release rate?
Heat Rate is an expression of the conversion efficiency of power generating engines or collectively plants. The typical unit for this is Btu/kWh, or British Thermal Units per kilowatt hour. For example 8,000 Btu/kWh means that 8,000 Btu of heat energy which is input into the engine will result in conversion to 1 kWh of electricity. The heat energy is of course input into the plant by combustion of many different types of fuels. It should not be misunderstood that using different fuels for the same engine will result in different Heat Rates for the engine. However the Heat Rate may be kept constant or even improved marginally by ensuring the engine is always properly maintained so that all working components are working at their peak efficiency. Obviously a poorly maintained engine will result in a deterioration of its Heat Rate, which means that more fuel will have to be burnt to generate the same amount of electricity. It is easy to understand why investors in power generation projects look at Heat Rate as a key indicator of the profitability of the plant concerned.
How does dirty overall heat transfer coefficient affect water flow rate?
A decrease in the overall heat transfer coefficient due to fouling or dirt buildup can reduce the efficiency of heat transfer in a system. This can lead to a decrease in the water flow rate as the system needs to compensate for the reduced heat transfer efficiency. Increased resistance to heat transfer can result in higher energy consumption and reduced performance of the system.
How do you increase processor clock rate?
By increasing the clock rate, the microprocessor's speed can be increased but with a cost of more heat generation, which may sometimes rupture the processor.
Does an increased rate of metabolism decrease the output of heat?
no even it will increase the out put heat
What are Gross Heat Rate and Net Heat Rate?
Gross Heat Rate: Gross electricity (Power) produced by a power plant per unit fuel energy consumption. This excludes all internal power consumptions. Net Heat rate is net power production at transformer per unit fuel energy consumption by power plant.
How do you calculate heat rate in gas power plant?
E=MC2 + o2 + H20 = Heat rate
What environmental factors increased the rate of transpiration?
Heat and wind.
Why is energy more important than power for a heating fuel?
Energy is more important than power for a heating fuel because energy measures the total amount of heat produced over time, while power only measures the rate at which the heat is delivered. This can be crucial for heating systems to ensure consistent and sustained heat output, rather than just focusing on the instantaneous heat generation.
How At high temperatures the rate of enzyme action decreases because the increased heat?
alters the active site of the enzyme
How do you calculate the efficiency of a power plant when you know its heat rate?
Efficiency = (860.4*100)/(Heat rate in kCal/kWh) or Efficiency = (860.4*4.18*100)/(Heat rate in kJ/kWh) Ex 1: if heat rate is 2500 kCal/kWh, then efficiency is 34.416% Ex 2: if heat rate is 9000 kJ/kWh, then efficiency is 39.96%
What is station heat rate and how it is measured?
The Station heat Rate is the amount of heat energy required to generate pqr unit of Electrical energy. The unit of measurement is Kcal/Kwh. The heat energy is obtained form coal, in a thermal power plant, or from gas in a gas power station.
Heat Rate in Natural gas based Combined Cycle Power Plant?
today rate of natural gas
How do you derive efficiency formula from heat rate for stem turbine?
Efficiency formula for a steam turbine is typically derived by dividing the electrical power output by the heat energy input. The heat rate of the steam turbine represents the amount of heat energy required per unit of electrical power generated, and by rearranging the equation, we can derive the efficiency formula as the reciprocal of the heat rate.
Do blood vessels increase in size to lose heat?
If a blood vessel has a larger diameter then there is an increased rate of blood flowing through that vessel per unit of time. This increased rate causes an increase in heat through the vessel. Thus constricting the diameter of the blood vessel will cause a decrease in the rate of blood flow, causing less heat and therefore increased heat loss.
