What is the relation between convection heat transfer coefficient? The convective heat transfer coefficient, h, can be defined as: The rate of heat transfer between a solid surface and a fluid per unit surface area per unit temperature difference. The convective heat transfer coefficient is dependent upon the physical properties of the fluid and the […]
What is the role of the pancreas in controlling blood sugar levels?
What is the role of the pancreas in controlling blood sugar levels? When blood sugar is too high, the pancreas secretes more insulin. When blood sugar levels drop, the pancreas releases glucagon to raise them. This balance helps provide sufficient energy to the cells while preventing the nerve damage that can result from consistently high […]
What is the effect of the degree of crystallinity on fatigue resistance of polymers?
What is the effect of the degree of crystallinity on fatigue resistance of polymers? However, qualitatively speaking the greater the crystallinity the harder the polymer, or the greater the strength as compared to the totally amorphous structure of a given average molecular weight. This is so, as the crystallinity reduces the degree of freedom for […]
What type of reaction is CH4 2 O2 → CO2 2 H2O?
Is x+ 2 a polynomial?
Is x+ 2 a polynomial? By definition, a polynomial in a variable x over a field (or a ring) is a finite linear combination of non-negative integer powers of x with coefficients from the field. Consequently √(x+2) or √x +2 are not polynomials. Is Square Root 7 a polynomial? In the given question we can […]
Does quality have any meaning in the superheated vapor region?
Does quality have any meaning in the superheated vapor region? Fraction of vapor in liquid-vapor region is called quality. since in superheated zone all the liquid has been vaporised hence it doesn’t have any meaning in superheated region. Does superheated vapor have quality? In thermodynamics, vapor quality is the mass fraction in a saturated mixture […]
What happens to inductor at steady state?
What happens to inductor at steady state? With a steady state DC current flowing through the inductor and therefore zero induced voltage across it, the inductor acts as a short circuit equal to a piece of wire, or at the very least a very low value resistance. What is the impedance of an ideal capacitor […]
What is a transformer symbol?
What is a transformer symbol? When a transformer has a centre tap, the symbol consists of two circles with a line joining one of the circles. Here is alternative qualified version, which also has dots to indicate the instantaneous voltage polarity. At what type of diagram does electrical symbols are applicable? An electronic symbol is […]
How is voltage related with a current B resistance?
How is voltage related with a current B resistance? The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant. Is voltage A Electric […]
How do you calculate maximum power dissipation?
How do you calculate maximum power dissipation? Therefore, the condition for maximum power dissipation across the load is RL=RTh. That means, if the value of load resistance is equal to the value of source resistance i.e., Thevenin’s resistance, then the power dissipated across the load will be of maximum value. How much power is dissipated […]
