Given the strings s1 and s2, not necessarily of the same length, create a new string consisting of alternating characters of s1

and s2 (that is, the first character of s1 followed by the first character of s2, followed by the second character of s1, followed by the second character of s2, and so on. Once the end of either string is reached, no additional characters are added. For example, if s1 contained "abc" and s2 contained "uvwxyz", then the new string should contain "aubvcw". Assign the new string to the variable s3.

What is pre-flush and post flush in petroleum engineering?

cluponka [151]

Answer:

Pre-Flush:

It is also known as In-line Equalization. In this stage of flow equalization, all the flow passes through the equalization basin. It helps in reduction of fluctuation in pollutants concentration and flow rate and helps to control short term surges with the use of basin.

Post-Flush:

Another name for this stage is Off-line Equalization. In this stage, only overflow above a predetermined standard is diverted into the basin. It helps in reducing the fluctuations in loading by a considerable amount and helps to reduce the pumping requirement. It is basically used to capture "first flush" from combined collection systems.

Air, at a free-stream temperature of 27.0°C and a pressure of 1.00 atm, flows over the top surface of a flat plate in parallel f

Morgarella [4.7K]

Answer:

Explanation:

Given that:

V = 12.5m/s

L= 2.70m

b= 0.65m

$T_{ \infty} = 27^0C= 273+27 = 300K$

$T_s= 127^0C = (127+273)= 400K$

P = 1atm

Film temperature

$T_f = \frac{T_s + T_{\infty}}{2} \\\\=\frac{400+300}{2} \\\\=350K$

dynamic viscosity =

$\mu =20.9096\times 10^{-6} m^2/sec$

density = 0.9946kg/m³

Pr = 0.708564

K= 229.7984 * 10⁻³w/mk

Reynolds number,

$Re = \frac{SUD}{\mu} =\frac{\ SUl}{\mu}$

$=\frac{0.9946 \times 12.5\times 2.7}{20.9096\times 10^-^6} \\\\Re=1605375.043$

we have,

$Nu=\frac{hL}{k} =0.037Re^{4/5}Pr^{1/3}\\\\\frac{h\times2.7}{29.79\times 10^-63} =0.037(1605375.043)^{4/5}(0.7085)^{1/3}\\\\h=33.53w/m^2k$

we have,

heat transfer rate from top plate

$\theta _1 =hA(T_s-T_{\infty})\\\\A=Lb\\\\=2.7*0.655\\\\ \theta_1=33.53*2.7*0.65(127/27)\\\\ \theta_1=5884.51w$

Encouraging your preschooler’s creative play

For your preschooler, time, materials and space to be creative are very important.

Preschoolers like to be spontaneous in their creative play, so it’s good to follow your child’s lead. But there’ll also be times when your child wants you to be more involved in her creative activities. By being actively involved, you can develop your child’s skills and understanding.

A piston-cylinder device contains 1.329 kg of nitrogen gas at 120 kPa and 27 degree C. The gas is now compressed slowly in a pol

Shtirlitz [24]

Answer:-0.4199 J/k

Explanation:

Given data

mass of nitrogen(m)=1.329 Kg

Initial pressure $\left ( P_1\right )$ =120KPa

Initial temperature $\left ( T_1\right )=27\degree \approx$ 300k

Final volume is half of initial

R=particular gas constant

Therefore initial volume of gas is given by

PV=mRT

V=0.986\times 10^{-3}

Using $PV^{1.49}$ =constant

$P_{1}V^{1.49}$ = $P_2\left (\frac{V}{2}\right )$

$P_2$ =337.066KPa

$V_2$ = $0.493\times 10^{-3} m^{3}$

and entropy is given by

$\Delta s$ = $C_v \ln \left (\frac{P_2}{P_1}\right )$ + $C_p \ln \left (\frac{V_2}{V_1}\right )$

Where, $C_v$ = $\frac{R}{\gamma-1}$ =0.6059

$C_p$ = $\frac{\gamma R}{\gamma -1}$ =0.9027

Substituting values we get

$\Delta s$ = $0.6059\times\ln \left (\frac{337.066}{120}\right )$ + $0.9027 \ln \left (\frac{1}{2}\right )$

$\Delta s$ =-0.4199 J/k
