You are traveling on a plane trip from Washington, D.C. to Cleveland, Ohio and the plane uses 1,260 MJ/passenger trip. If you ma

de the trip by car it would take 18 gallons/passenger trip. There are 142 MJ in a gallon of kerosene, a type of jet fuel. How many gallons of kerosene does it take to make the trip by plane?

Answer:

8.87 gallons of kerosene

Explanation:

Step 1: Given and required data

  • Energy to travel by plane per passenger trip: 1,260 MJ/passenger trip
  • Energy per gallon of kerosene: 142 MJ/gal

Step 2: Calculate how many gallons of kerosene it takes to make the trip by plane

We can calculate the amount of kerosene required by combining the factor provided in Step 1.

1 gal/142 MJ × 1,260 MJ/passenger trip = 8.87 gal/passenger trip

8.87 gallons of kerosene are required to make the trip by plane.

The pressure in a section of horizontal pipe with a diameter of 2.5 cm is 139 kPa. Water ï¬ows through the pipe at 2.9 L/s. If t
My name is Ann [436]

Answer:

d = 2*0.87 = 1.75 cm

Explanation:

by using flow rate equation to determine the  speed in larger pipe

\phi =\pi r^2 v

v = \frac{\phi}{\pi r^2}

  = \frac{2900 cm^3/s}{3.14(1.25cm)^2}

= 591.10 cm/s

 = 5.91 m/s

by Bernoulli's EQUATION

p1 +\frac{1}{2} \rho v1^2 = p2 +\frac{1}{2} \rho v2^2

139000+ \frac{1}{2}*1000*5.91^2 = 101000 +\frac{1}{2}*1000* v2^2

solving for v2

v2 = 10.53 m/s

diameter can be determine by using flow rate equation

q = v \pi r^2

r^2 = \frac{q}{\pi v}

     = \frac{2900}{3.14*1053}

r = 0.87 cm

d = 2*0.87 = 1.75 cm

24. A total of 165 J of work is done on a gaseous refrigerant as it undergoes compression. If the internal energy of the gas inc
Yuliya22 [10]

The total amount of energy transferred as heat is equal to 288 Joules.

<u>Given the following data:</u>

  • Internal energy = 123 Joules
  • Work done = 165 Joules

To calculate the total amount of energy transferred as heat, we would apply the first law of thermodynamics.​

<h3>The first law of thermodynamics.</h3>

Mathematically, the first law of thermodynamics is given by the formula:

\Delta E = Q - W

<u>Where;</u>

  • \Delta E is the change in internal energy.
  • Q is the quantity of heat transferred.
  • W is the work done.

Substituting the given parameters into the formula, we have;

123 = Q - 165\\\\Q=123+165

Q = 288 Joules.

GuDViN [60]

Explanation:

Webb gives us new and unique eyes of places that we have never been able to reach.” With NASA and the European Space Agency's Hubble pushing 32 years in orbit, the bigger, 100 times more powerful Webb is widely viewed as its successor even though the two are vastly different.
