Answer : σ = Stefan Boltzmann regular = 5.6697 x 10-eight W/ (m² K4).

Answer : Heat transfer from the shifting fluid to solid surface is given through the equation. Q = h A = [Tw – T∞] This equation is called Newton’s regulation of cooling.Where h = Local warmth switch coefficient in W/m2K.A = Surface vicinity in m2Tw = Surface [or] Wall temperature in K.T∞ = Temperature of…

Answer : It is defined because the ratio of inertia pressure to viscous force. Re = Inertia pressure / Viscous pressure

Answer : Reynolds number [Re].Nusselt quantity [Nu].Prandtl quantity [Pr].

Answer : Laminar glide: Laminar glide is once in a while referred to as stream line flow. In this sort of waft, the fluid moves in layers and every fluid particle follows a clean continuous route. The fluid particles in every layer continue to be in an orderly series with out mixing with each other

Answer : The fluids which obey the Newton’s law of viscosity are referred to as Newtonian fluids and those which do not obey are called no-newtonian fluids.

Answer : It is the ratio of Nusselt quantity to the manufactured from Reynolds wide variety andPrandtl range.       St = Nu / Re x Pr.

Answer : It is described because the ratio of made from inertia force and buoyancy pressure to the rectangular of viscous pressure. Gr = Inertia pressure x Buoyancy force / [Viscous force]2

Answer : It is fluid movement is produced due to trade in density as a consequence of temperature gradients, the mode of heat transfer is said to be unfastened or natural convection.

Answer : MoistureDensity of clothPressureTemperature e. Structure of fabric.
