What are the units for heat transfer coefficient? The overall heat transfer coefficient, or U-value, refers to how well heat is conducted through over a series of resistant mediums. Its units are the W/(m2°C) [Btu/(hr-ft2°F)]. How do you calculate total heat flow? To calculate the amount of heat released in a chemical reaction, use the […]
What are the 4 components of a cell?
What are the 4 components of a cell? All cells share four common components: (1) a plasma membrane, an outer covering that separates the cell’s interior from its surrounding environment; (2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; (3) DNA, the genetic material of the cell; […]
What is the principle of electric circuit?
What is the principle of electric circuit? Ohm’s Law explains the relationships between voltage (E), resistance (R), and current (I). In two circuits of equal voltage, the current will be proportionately greater in the circuit of lower resistance. In circuits of equal resistance, the current flowing will be directly proportional to the voltage applied. What […]
On what principle does a pressure cooker work?
On what principle does a pressure cooker work? A pressure cooker is based on the principle that with the increase in pressure, boiling point of water increases. It works by capturing the steam which increases the pressure in the vessel. How does a pressure cooker cook? A pressure cooker is a sealed chamber that traps […]

Which transformer is used in power supply?
Which transformer is used in power supply? Transformers are most commonly used for increasing low AC voltages at high current (a step-up transformer) or decreasing high AC voltages at low current (a step-down transformer) in electric power applications, and for coupling the stages of signal-processing circuits. What are the 2 types of power supply? Two […]
