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......
In a real machine why is the work output always less than the work input?
Every real machine is subject to forces that reduce output. These include actual forces such as friction, or human controlled forces such as imperfect machining. This reduces the output to less than the ideal.
Why DC motors are not operated to devolop maximum power in practice?
It is almost inevitable that some energy is lost.If the engine produces heat, as in a gasoline engine, there is a theoretical limit - that of the theoretical Carnot engine - which is itself less than 100%. For example, if the ambient temperature is 300 kelvin and the engine works at 900 kelvin, the theoretical efficiency is 66.666... percent. But the real efficiency would be even less than that.
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.
Is competing side reaction a reason why actual yield is less than theoretical yield?
No, competing side reaction is a reson why the actual yield is more than the theoretical yield.
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
Is impure reactants present a reason why actual yield is less than theoretical yield?
yes
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 could an actual yield be more than a theoretical yield?
If actual yield is higher than theoretical yield then it means the required products contains impurities.
Why is the actual discharge through an orifice less than theoretical discharge?
Because the baby goats aren't allowed to swim in the ocean. =(
The efficiency of an actual machine is always less than what percent?
It is always less than 100% Theoretical machines can have efficiencies of 100% but in practice there is always some energy loss Efficiencies of more than 100% are not allowed by the laws of thermodynamics!
Why COP actual lower than COP theoretical?
Theoretical calculations take into account many factors that in fact should not be involved
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.
