Why dual combustion cycle is called as limited pressure cycle?
In dual combustion cycle heat is added at constant volume which increases the efficiency of cycle, whereas heat addition at constant pressure limits the maximum pressure of the cycle.
Why we don't use high pressure in pneumatics?
one reason air is much harder to control the heat and air has a lot of water in it and a hydraulic system dose not need water in the hydraulic oil. There is no way at the high pressure that a hydraulic system has to work at,it would not be possible to control the heat.
Floating head pressure?
Floating head pressure refers to the pressure at the top of a fluid column in a system where the head or height of the fluid is variable. It is commonly encountered in applications like heat exchangers, where it influences the efficiency of heat transfer and can impact the overall performance of the system. Managing floating head pressure is essential for optimizing operations and ensuring safe and effective fluid movement. Proper design and control strategies can help mitigate potential issues associated with fluctuating pressures.
What is the function of Wire Gauze?
it helps in providing constant heat
What happen if you heat steam?
If you heat steam under pressure you get "superheated steam" under higher than original pressure
What special name is given to a heat change at constant pressure?
A heat change at constant pressure is called enthalpy change, often denoted as ΔH. It represents the change in total heat content of a system during a process occurring at constant pressure.
The heat content of a system at constant pressure?
The heat content of a system at constant pressure is enthalpy, denoted as H. Enthalpy includes both the internal energy of the system and the energy required to displace the environment, given by the product of pressure and volume. It is commonly used in thermodynamics to analyze and predict energy changes in chemical reactions and physical processes.
What other name is given to the heat of a reaction?
Enthalpy is another term used to refer to the heat of a reaction. It represents the total heat content of a system at constant pressure.
What is A measure of the heat content of the system h?
The measure of the heat content of a system is known as enthalpy, denoted by the symbol H. Enthalpy includes internal energy and work done by the system on its surroundings, and is used to quantify the heat absorbed or released during a process at constant pressure.
Choose the name and symbol for internal heat of a system at constant pressure?
The name for the internal heat of a system at constant pressure is enthalpy, symbolized as "H."
What is the enthalpy equation used to calculate the change in heat energy of a system at constant pressure?
The enthalpy equation used to calculate the change in heat energy of a system at constant pressure is H q PV, where H is the change in enthalpy, q is the heat added or removed from the system, P is the pressure, and V is the change in volume.
The name and symbol for internal heat of a system at constant pressure?
Energy, E.There are two types of chemical reactions. Reactions which produce energy are called exothermic reactions, while reactions which consume energy are called endothermicreactions. Generally, an exothermic reaction can be written such as Reactants → Products + Energy An endothermic reaction can be written such as: Reactants + Energy → Products
Heat exchange in chemical reactions is due to a change in what?
Enthalpy-The heat added to or loss by a system at constant pressure
Why the molar specific heat at constant pressure is larger than the molar specific heat at constant volume?
The specific heat at constant pressure is larger than the molar specific heat at constant volume because if heat is added to a system it not only heats up but expands in volume. Therefore the system is doing work against the external pressure and the heat is not only stored as kinetic and potential energy but is also required to perform work. In general more heat can be stored in a system at constant pressure than one at constant volume. The specific heat at constant pressure is larger than the molar specific heat at constant volume because if heat is added to a system it not only heats up but expands in volume. Therefore the system is doing work against the external pressure and the heat is not only stored as kinetic and potential energy but is also required to perform work. In general more heat can be stored in a system at constant pressure than one at constant volume.
What is the significance of the keyword q delta-h at constant pressure in the context of thermodynamics?
In thermodynamics, the keyword q delta-h at constant pressure represents the heat transfer that occurs in a system at constant pressure. This equation is significant because it relates the heat transfer (q) to the change in enthalpy (delta-h) of the system. Enthalpy is a measure of the total energy of a system, including both internal energy and pressure-volume work. By considering heat transfer at constant pressure, this equation helps in understanding and analyzing energy changes in chemical reactions and physical processes.
What is the property that describes heat change in a constant pressure?
The property that describes heat change at constant pressure is known as enthalpy (H). When a system undergoes a process at constant pressure, the heat exchanged is equal to the change in enthalpy (ΔH). This relationship is crucial in thermodynamics, particularly in chemical reactions and phase changes, where it helps quantify the energy absorbed or released during the process.
What factor must be constant for enthalpy to be equivalent to the total flow of heat?
For enthalpy to be equivalent to the total flow of heat, the process must occur at constant pressure. Under these conditions, the change in enthalpy (ΔH) directly corresponds to the heat added or removed from the system. If pressure changes, the relationship between enthalpy and heat transfer becomes more complex due to work done by or on the system.
