The actual coefficient of performance (COP) of a vapor-compression refrigeration (VCR) cycle is less than the theoretical COP due to several inefficiencies in the system. These include irreversibilities such as friction in the compressor, heat losses in the condenser and evaporator, and non-ideal gas behavior. Additionally, factors like suboptimal component performance and varying operating conditions further reduce efficiency, preventing the system from achieving the ideal performance predicted by the theoretical COP.

Which cycle is best in heat engine?
The ideal cycle for a heat engine is often considered to be the Carnot cycle, as it provides the maximum possible efficiency between two temperature reservoirs. This theoretical cycle operates through four reversible processes: two isothermal and two adiabatic. Although real engines cannot achieve Carnot efficiency due to practical limitations and irreversibilities, the Carnot cycle serves as a benchmark for evaluating the performance of actual heat engines. Other cycles, like the Otto or Diesel cycles, are commonly used in practice, but they are less efficient than the Carnot cycle.
Define the term negative slip in reciprocating pump?
When the actual flow (Qa) is greater than theoretical flow (Qt) in a reciprocating pump it is negetive slip.
Why there should be difference in actual loads and theoretical calculated loads?
The theoretical loads being calculated should be higher than the actual loads that will be used in reality because the weight capacity of a structure, vehicle etc. should exceed the amount of weight it is intended to actually hold. This is true for any type of load, driveshafts, shirt buttons, whatever.
Why coefficient of performance of absorption cycle is less than compression cycle?
In case of vapour compression cycle (VCC) the COP is given by (desired effect / work input). in the other words it can be defines as what we want and what we are paying for that... so in VCC the paying amount is very less as due to low temperature difference that why its value is more than 1. but in case of vapour absorption system the COP is given by (heat taken by evaporator/ heat given to generator). the heat input taken by evaporator is less as compared to heat given to generator.. that why its COP is less than 1......
What is actual quality?
Actual quality refers to the true level of performance, reliability, and overall value of a product or service as experienced by the user, rather than how it is marketed or designed. It encompasses factors such as durability, functionality, and customer satisfaction. Evaluating actual quality often involves direct user feedback and real-world performance metrics, rather than just theoretical specifications or expectations. Ultimately, it reflects how well a product meets the needs and expectations of its users.
Is actual yield greater or less than theoretical yield?
The actual yield is less than the theoretical yield.
Is actual yield greater or less than the theoretical yield?
The percent yield is the ratio of the actual yield to the theoretical yield. A mole ratio is a conversion factor derived from the coefficient of a balanced chemical equation interpreted in terms of moles.
What is the difference between actual yield and theoretical yield?
Theoretical= calculated
Why actual cop of vapour compression refrigeration is less than theoretical cop?
Mahit Nahi
What is the difference between actual and theoretical compensation payouts?
Actual compensation will always be less than theoretical payouts. For example, it the posted payout is 50%, the actual payout will be somewhere closer to half of that amount, or 25% actual payout.
Why is the actual discharge through an orifice less than theoretical discharge?
Because the baby goats aren't allowed to swim in the ocean. =(
Why is the actual discharge through an oriffice less than the theoretical discharge?
The actual discharge through an orifice is less than the theoretical discharge primarily due to factors such as fluid viscosity, turbulence, and energy losses associated with flow separation and friction. The theoretical discharge assumes ideal conditions with no resistance or energy loss, while real-life conditions involve these inefficiencies. Additionally, the orifice shape and size can also impact the flow characteristics, further reducing the actual discharge compared to the theoretical predictions.
Why could an actual yield be more than a theoretical yield?
An actual yield can be more than a theoretical yield due to incomplete reaction conversion, impurities in reactants, or unexpected side reactions. These factors can result in more product being formed than predicted by theoretical calculations.
Why actual yield is always less than theoratical yield?
Actual yield is always less than theoretical yield because: 1) Much amount of product is lost in experimental techniques i.e. filtration, evaporation etc. 2) Much amount of product is lost in energy i.e. heat energy.
If you ovulated late are your pregnancy weeks supose to be less than your actual lmp date?
Yes. Unless you have a 28 day cycle, your personalized due date will be less than your LMP due date.
Does heat of hydrogenation of benzene is less than the theoretical value?
yes
Is competing side reaction a reason why actual yield is less than theoretical yield?
Yes, competing side reactions occurring during the reaction can lead to a lower actual yield compared to the theoretical yield. Side reactions may produce undesired byproducts or result in incomplete conversion of reactants, reducing the overall yield of the desired product. Factors such as reaction conditions, impurities, and catalysts can influence the extent of side reactions and their impact on the final yield.
