What is steam economy in Evaporator?
Steam economy is the ratio between total steam evaporated and steam consumed Se=Steam evaporated/steam flow at start should be above 1 for multi effect systems
Why does a squirrel often get zapped when climbing on power lines?
The squirrel bridges the wire insulators, providing a path for current to flow from the wire to ground, usually through a pole and the grounding wires attached to it.
Why does the AC work when driving but drops when idling on a 1986 Suzuki Samuari in which you installed a 1995 Suzuki Sidekick 1.6 a6V?
The fact that the engine was replaced should not be an issue. Here is my assesment based on your question; either the ac system has a smaller capacity (smaller compressor, condenser, receiver dryer), and for that reason while driving you get a higher flow of freon thru the system compared to engine at idle, or there may be some debris in the system causing a restriction, not allowing enough flow of freon thru the evaporator. Once again, if you are driving, the compressor will spin at a faster rate and therefore provide more flow of freon thru the evaporator, therefore the cooler air. It is also possible the pulley on either the crank or on the compressor is the incorrect size.
What is the difference between an open circuit and an open aev?
This is copied from Section 6.11, Question 8 in "Modern Refrigeration and Air Conditioning." The answer is (B), "The open circuit prevents flow. The open AEV allows flow to occur." Although a bit obscure, the answer is correct because, within the context of an electrical circuit, an "open circuit" (i.e. disconnected wire) would prevent the flow of electrical current. Within the context of a refrigeration circuit, an open AEV (automatic expansion valve) would permit the flow of refrigerant into an evaporator coil to provide cooling.
How the liquid flow meter is working?
The turbine flow meter translates the mechanical action of the turbine rotating in the liquid flow around an axis into a user-readable rate of flow. The turbine tends to have all the flow traveling around it. The turbine wheel is set in the path of a fluid stream. The flowing fluid impinges on the turbine blades, imparting a force to the blade surface and setting the rotor in motion. When a steady rotation speed has been reached, the speed is proportional to fluid velocity. Turbine flow meters are used for the measurement of natural gas and liquid flow
When air flow is decreased across the evaporator the evaporator temperature will?
rise
What is an upward flow of air?
An upward flow of (warm) air is known as a Thermal .
What is upward flow of stomach acid into the esophagus called?
Gastroesophageal reflux disease is the upward flow of acid from the stomach into the esophagus.
What is the relationship between evaporator air flow and suction superheat?
air flow and liquid change of state
What is Steady flow energy equation for evaporator?

Why does the nile flow upward?
The river does not flow upwards. The Earth is round, the Nile simply flows South to North - on a map it just looks like it flows "upward"
What is the purpose of an externally equalized thermal expansion valve?
An externally equalized thermal expansion valve is used to regulate the flow of refrigerant into the evaporator based on the evaporator's temperature. By sensing the refrigerant pressure at the outlet of the evaporator, the valve can adjust the flow rate to maintain proper superheat levels, ensuring efficient cooling performance in the system.
Vertical pipe on a building for the upward flow of gas or liquid?
That is a chimney.
Dry expansion evaporator?
In dray expansion evaporator, the liquid refrigerant is generally fed by an expansion valve. the expansion valve controls the rate of flow of refrigerant to the evaporator. In the evaporator the liquid refrigerant is vaporized and superheated by the time it reaches to the end of evaporator. At inlet of the evaporator, the refrigerant is predominantly in the liquid form with a small amount of vapor formed as a result of flashing at the expansion valve. the liquid refrigerant passes through the evaporator, more and more refrigerant is vaporized by the load. according to the load, the liquid will come into evaporator and vaporize and reaches to superheat at the end of the evaporator. The inside of the evaporator is far from dry but wetted with liquid so named as dry expansion evaporator.
What is an example of upward communication?
Upward communication is the flow of information from the lowest level to the highest level in an organization. Examples of upward communication includes;Reports of progress from subordinates to management.Complains/grievances.Suggestions.New ideas to Management.
Why a reducing orifice in the steam supply line of such an evaporator?
A reducing orifice in the steam supply line of an evaporator is used to control the flow rate of steam entering the evaporator. This helps in maintaining the desired operating conditions and ensuring efficient heat transfer within the evaporator. Additionally, it can help prevent overheating and equipment damage by limiting the amount of steam entering the system.
How is the skin like the air conditioning system?
The skin sweats a liquid which evaporates and cools the body. An Ac system has an evaporator. The liquid goes in, gets evaporated and air flow over the evaporator cools the structure.
