The dimensional number associated with mass transfer is1. Schmidt Number2. Nusselt Number3. Biot Number4. Mach Number

Answer» Correct Answer - Option 1 : Schmidt Number

Concept:

Schmidt number is a dimensionless number and defined as the ratio between momentum diffusivity and mass diffusivity, and is used to characterize the fluid flows where both momentum and mass transfer are involved.

It is given by 

\(Schmidt\;number\;\left( {Sc} \right) = \frac{{Momentum\;diffusivity}}{{Mass\;diffusivity}} = \frac{{\nu \;\left( {kinematic\;viscosity} \right)}}{{D\;\left( {mass\;diffusivity} \right)}}\)

For higher Schmidt numbers, momentum diffusion dominates, and for lower Schmidt numbers, mass diffusion dominates

Schmidt number can be considered analogous to Prandtl number, while the

Prandtl number describes the diffusion of heat (thermal boundary layer).

Schmidt number describes the diffusion of mass (concentration boundary layer).

47.

Define crank effort and crank pin effort.

Answer»

It is the graphical representation of the turning moment or crank effort for various position of the crank.

In a city 40% are vegetarians. In a random sample of 6 persons, find the probability that (i) 3 are vegetarians (ii) at least one is a vegetarian.

Answer»

Given : p = 40% = 0.4 q = 1 – p = 70.6 6n = 6

Let ‘x’ be the number of vegetarians is a Binomial variate with the parameters n = 6 p = 0.4 and q = 0.6, then,

The p.m.f. is –

p(x) = ncxpxqn – x ; x = 0,1,2, …… n

= 6Cx (0.4)x (0.6)6 – 3 ; x = 0,1,2 ……… 6

(i) p(3 are vegetarians)

= p(x = 3) = 6C3 (0.4)3 (0.6)6-3 

= 20 x 0.064 x 0.216 = 0.2765

(ii) p(atleast one is a vegetarian)

= p(x ≥ 1)= 1 – p(x < 1) = 1 – p(x = 0)

= 1 – 6C0 (0.4)0 (0.6)6-0 

= 1 – 1 x 1 x 0.046 

= 0,9554

50.

The largest part of most diets of vegetarians is made up of?1. Carbohydrates2. Proteins3. Nucleic acid4. Lipids

Answer» Correct Answer - Option 1 : Carbohydrates

The correct answer is Carbohydrates.

  • Carbohydrates-
    • The largest part of most diets of vegetarians is made up of Carbohydrates.
    • Foods that are rich in carbohydrates are an important part of a healthy diet.
    • Starch is the main form of carbohydrate in our food.
    • Carbohydrates provide the body with glucose, which is converted to energy used to support body functions and physical activities. 
    • Carbohydrates are found in both healthy and unhealthy foods such as bread, beans, milk, popcorn, potatoes, cookies, corn, etc.
