Answer:

6.47 gallon per person per day

Explanation:

Given

The total amount of water available for domestic use is  5500 gallon

Let us consider that the entire available water goes to domestic use.

The total population of the village is 850.

The amount of water available to each villager is

\frac{5500}{850}\\6.47 gallon per person per day

Water at 20oC, with a free-stream velocity of 1.5 m/s, flows over a circular pipe with diameter of 2.0 cm and surface temperatur
Lisa [10]

Answer:

Average heat transfer coefficient =  31 kw/m^2 k

Heat transfer rate per meter length of pipe =  116.808 KW

Explanation:

water temperature = 20⁰c,  

free-stream velocity = 1.5 m/s

circular pipe diameter = 2.0 cm = 0.02 m

surface temperature = 80⁰c

A) calculate average heat transfer coefficient

we apply the formula below :

m = αAv

A (area) = \pi /4 (d)^2

m = 10^3 * \pi  / 4 ( 0.02)^2 * 1.5

   = 10^3 * 0.7857( 0.0004) * 1.5

   = 0.4714 kg/s

Average heat transfer coefficient  

h = \frac{m(cp)}{A}  ,  A = \pi DL

L = 1 m , m = 0.4714 kgs , cp = 4.18

back to equation

h = \frac{0.4714*4.18}{\pi * 0.02 }   = 1.970 / 0.0628 = 31.369 ≈ 31 kw/m^2 k

B) Heat transfer rate per meter length of pipe

Q = ha( ΔT ),  a = \pi DL

   = 31 * 0.0628 * ( 80 - 20 )

  = 31 * 0.0628 * 60 = 116.808 KW

Time complexity of merge sort
vovangra [49]

Answer:

The correct answer is "O (n\times Log n)". A further explanation is given below.

Explanation:

  • Throughout all the three instances (worst, average as well as best), the time complexity including its Merge sort seems to be O (n\times Log n) as the merge form often splits the array into two halves together tends to linear time to combine multiple halves.
  • As an unsorted array, it needs an equivalent amount of unnecessary capacity. Therefore, large unsorted arrays are not appropriate for having to search.

your friend's parents are worried about going over their budget for th month. Which expense would you suggest is NOT a need?
prisoha [69]

Things for entertainment aren't needs. For example, designer clothes, the new iPhone that just came out, fancy dining, that expensive shirt that has the same model somewhere cheaper, and sports cars are all wants, not needs.

Needs are like water, a shelter to live in, food, clothing, and running electricity. Water is essential for survival, since you could die of thirst in 2 days. A shelter will protect you from insects, weather, and uninvited guests. Living without food will kill you in 2 weeks, as you need food for energy and so let your body repair itself faster if you got injured. You need clothing to keep you warm and to cover your private parts. Running electricity is needed because electricity makes most of your needs easier to acquire.

I hope this helps! Good luck!

A Transmission Control Protocol (TCP) connection is in working order and both sides can send each other data. What is the TCP so
kkurt [141]

Answer:

ESTABLISHED

Explanation:

What is TCP?

A Transmission Control Protocol (TCP) is a communication protocol which allows the exchange of data between computers in a network.  

When a Transmission Control Protocol connection is up and running meaning that both sides can send and receive data then the corresponding TCP socket states is known as "ESTABLISHED".

The most common socket states are:

LISTEN:

Before a TCP connection is made, there needs to be a server with a listener that will listen on incoming connection request.

ESTABLISHED:

When a TCP connection is up and running meaning that both sides can send and receive data.

CLOSED:

The CLOSED state means that there is no TCP connection.

There are a total of 11 TCP socket states:

1. LISTEN

2. SYN-SENT

3. SYN-RECEIVED

4. ESTABLISHED

5. FIN-WAIT-1

6. FIN-WAIT-2

7. CLOSE-WAIT

8. CLOSING

9. LAST-ACK

10. TIME-WAIT

11. CLOSED
