For the flow over a flat plate value of the critical Reynold's Number is 5*10 5

for the Re>5*10 the flow is known to be turbulent

and if Re<5*10 then the flow is Laminar

In the first row Reynold's number is 54694.17 (> 5*10 ) hence the flow is turbulent in this observation

In the second row, Reynold's number is 4600.745 (< 5*10 hence the flow is Laminar in this observation

In the second row, Reynold's number is 3910.633 (< 5*10 hence the flow is Laminar in this observation

Answer.) Keplerian Telescopes πŸ”­. :

(a) Kepler telescope The Kepler telescope πŸ”­ as shown in the figure consists of two converging Lens, one is called Objective lens and another is called eyepiece Lens ....

Now it is given that ;

the object is lying in the front focal plane of the first lens

therefore,

magnification m = -fo/fe = -2

Implies , fo ( objective focal length)

= 2 • fe ( eyepiece focal length) ...

image size = m • object size

image size = -2 •5 mm = -1 cm

for normal adjustment Lenght

L = fo + fe = 3 • fe

for calculation and N.A of the objective lens ;

f 40 7 δΈͺ diffraction limited spet size (da) fo ak te Now from Ray optics, W. A (numerical Affesture) = 224 Δ« da no-500 nm da hence , the numerical aperture NA = 0.159

answer.....

ANSWER:-

​​​​​​

Every employee before opting for a job lays emphasis on few important things such as job profile, compensation to be paid, added benefits to the compensation package. No employee is willing to work for cash alone they expect some extra benefits added to their salary, also known as fringe benefits. An employee would definitely before signing a job offer like to negotiate the salary and benefits. Few questions you would like to ask your employer concerning benefits are:

1. Does the employer pay for insurance coverage? If yes, then how much would be the individual insurance cover/or family coverage?

2. Do I have the option of reviewing the insurance plan options provided by the employer?

3. How must sick time, vacation time or holidays would be provided and from what time period will I start earning these benefits?

4. What would be the pension plans available?

5. If required will the company provide for any training or educational benefits?

The benefits package that you would like to negotiate for yourself would be regarding the insurance cover that the company is providing, moving allowances for projects etc., pension plans according to the need of family at the time of retirement, and all such benefit plans which do not meet your requirement.

Given problem is a typical mixing problem

dy dt ratein rategut

Let y(t) is the salt in tank at time t

The water entering has no salt, rate in =0

The thoroughly mixed solution has concentration of 10L/min . The tank has 1119 L of brine with 15 kg of salt

Rate out =( y/1119) kg/ L * 10 L/min = 10 y/ 1119 kg/mim

Hence, differential equation is dy dt 10y 1119

dy Y 10 -dt 1119

dy =-11 10 Γ’€¢dt 1119 S

10 In y = - + tc 1119

y = e 1119 +c

at t=0, y= 15

15= C

c= 15

Therefore, y= 10 y = 15e 1119 =

After 20 minutes, t= 20

10.200 y = 15e 1119 kg

y= 12.54496 kg
