Answer / sharadha

O.H.T.C is usually used in conduction-convection systems
where there are several resistances in series formed on the
heat transfer surface.
I.H.T.C is used only for convection systems where der is
only a single resistance to the heat transfer surface.this
is d basic difference.

Answer / prokash

There are two type of heat transfer co-efficient.
Internal heat transfer co-efficient and external heat
transfer co-efficient. they are separately called individual
heat transfer coefficient. and the combined effect of them
to heat transfer is called Overall heat transfer coeficient.

Answer / apurva

Overall heat transfer coefficient is the conductance for all the materials through which heat is flowing. It can be obtain by adding individual heat transfer coefficients for each material.
Just like getting electrical resistance from the circuit, heat transfer coefficient varies with the material presence of material in the series or parallel attachments.

Answer / aroh shrivastava

the sum of indivisual heat transfer coeffincint that is
film coefficint is called UHTc. and when it take
indivisually it is called IHTC.

ACCOUNTING AND FINANCIAL ENGINEERING - EXAMPLE 34.24 : (a) The net present value of an engineering project is given by V. Let Q = summation of [ T / (1 + I) ^ N ] from N = A to N = B, where P = project cost, T = tax inflow, N = duration. If V = P + Q where P = -$1000, T = $275, I = 0.12 (means 12 % , capital cost of project per year), A = 1 year, B = 5 years, calculate the value of V. (b) The present value tax shields are W = $ (11.9725, 9.1486, 6.5579, 4.1811, 2.0005) in 5 beginning balances of an engineering project. Find the adjusted present value of the engineering project X, when X = V + (summation of the values of W).

QUANTUM BIOLOGY - EXAMPLE 33.10 : The wavefunction starts out in a superposition of possible states in a closed black box like this : Ψ (kitty) = 0.7071 Ψ (alive) + 0.7071 Ψ (dead) where Ψ (kitty) = wavefunction of a kitten, Ψ (alive) = wavefunction of a living kitten, Ψ (dead) = wavefunction of a dead kitten. By prediction and calculation, find the probability of : (a) a living kitten inside the black box; (b) a dead kitten inside the black box.
