### Why is the mass of a nucleus always less than the sum of

Answers (1) During the formation of the nucleus certain number of neutrons and protons are brought together, the energy will be released during this process. is called the binding energy of the nucleus. This energy is spent by the nucleus at the expense of their masses. Therefore, the mass of the nucleus formed is less than the sum of the ...

### Compressor Mass Flow - Some Thought Experiments

Aug 12, 2021 When you drop the suction pressure entering a typical compressor, you drop the mass flow rate because the mass entering the compressor is reduced; a lower mass flow rate means moving fewer lbs of refrigerant, which (by itself) means lower capacity. Now, let's move to the second part, which is re-expansion. This one applies more to reciprocating ...

### Evaporators Dairy Processing Handbook

Evaporator design. It takes a large amount of energy to boil off water from a solution. This energy is often supplied as steam. To reduce the amount of steam needed, the evaporator is normally designed as a multiple-effect evaporator. Two or more effects operate at progressively lower vacuums and thus with progressively lower boiling points.

### Why is it important to have fat mass and fat free mass?

Fat-Free Mass (FFM), also called Lean Body Mass (LBM), is the total amount of nonfat (lean) parts of the body. It consists of approximately 73% water, 20% protein, 6% mineral, and 1% ash. To convert body fat percentage to kilograms, multiply the body fat percentage by total body weight. If you weigh 80 kg and are 20% body fat, this means that ...

### The Essentials of Continuous Evaporation AIChE

Figure 4 shows the mass flows in a three-effect evaporator. The vapor from the first effect (M V1) becomes the heating source for the second effect (M S2). This is possible because the second effect’s boiling temperature has been lowered to 68C (at 29 kPa), which is less than the saturated temperature of the first effect, 82C (at 51.8 kPa).

### atoms - Why is the atomic mass unit less than the mass

Jan 02, 2021 The atomic mass unit is $1.6605 \times 10^{-27}$ kg. This is less than the mean of the masses of 6 protons and 6 neutrons. How do we account for the lower mass ? My understanding is that some of the mass is in the form of energy somewhere, in the bonding maybe or in the kinetic energy. Can someone clarify where this mass is please ?

### What Is a Refrigerator Evaporator; Why Is It Important?

Jan 12, 2021 The refrigerator evaporator is one part of the refrigeration cycle that makes the inside of your refrigerator cold. After the refrigerant gas has gone through the condenser coils located at the back of the refrigerator, it starts to cool down and turn into a liquid. It’s at this liquid stage that the refrigerant reaches the expansion valve.

### What Happens as Refrigerant Flows Through the Evaporator?

Jan 28, 2020 When refrigerant flows into a direct exchange evaporator, it is mostly saturated liquid, with some vapor. As refrigerant travels through the evaporator, it absorbs heat from the air. As it absorbs heat, it vaporizes. If the system operates according to design, the refrigerant will be 100% vapor as it nears the exit of the evaporator.

### Why mass is additive? - Physics Forums

Jul 15, 2013 The additive property of mass is simply an observed property of nature. As has been pointed out, it applies only to mechanical interactions between bodies in which the energy of the bond between masses divided by c 2 is much less than the rest masses of the separate bodies.

m = your mass in slugs (English unit) Convert mass in slugs to Kilograms (standard metric unit) with the conversion factor: 1 slug = 14.59 kg (In order to convert, multiply the answer you got in step 3 by 14.59 kg/slug so that the slug units cancel and your mass is in kg.) So, if I weigh 98 lbs on Earth, then my mass is 3.04 slugs or 44 kg.

### Why is it that object of more mass attains less velocity

Mar 08, 2012 The momentum change is equal to the Force applied times the time, for which it is applied. So, for a certain Force times Time (Impulse) you have a trade-off between Mass and velocity change - small mass/big velocity change or large mass/small velocity change. That's a perfectly reasonable argument - if you are prepared to accept it.

### Work done by evaporator condenser expansion valve

May 23, 2013 3. Technically, there is no work done by the condenser or evaporator. Work is the exchange of mechanical energy wheras heat is the exchange of thermal energy.

### Things To Know about Why AC Evaporator Coil Leak

Sep 10, 2021 The evaporator coil can be weakened by erosion. The coolant that flows through the spindles of the evaporator wears away over time the inner lining. It makes the spindles weaker. The spool develops troughs and breaks in a fragile state. It causes the coolant to leak.
