Answer:
The required thickness of the tank wall is 87.7668 mm.
Step-by-step explanation:
Given :
Volume of vessel is V=1.5 m³.
A spherical pressure vessel is of compressed natural gas at P=22 MPa.
If the tank is made of A516 grade 60 steel with a maximum normal stress 150 MPa.
i.e.
To find : What is the required thickness of the tank wall?
Solution :
The diameter of the vessel is given by,
Convert into mm,
The thickness of the wall tank is given by,
Therefore, the required thickness of the tank wall is 87.7668 mm.
Answer:
After t = 4 the rocket will hit the ground.
Step-by-step explanation:
We are given a parametric equation as x = 3t² and y = - 4t + 16.
If we assume that the x is a measure of horizontal distance, y is the measure of vertical distance and t is the time of travel of the rocket, then by making y = 0, we will get the time to hit the ground.
Hence, - 4t + 16 = 0
⇒ t = 4
Therefore, after t = 4 the rocket will hit the ground. (Answer)
If you would like to know how much will the watermelon cost, you can calculate this using the following steps:
$1.27 ... 1 pound
$c = ? ... 5.5 pounds
1.27 * 5.5 = 1 * c
c = 1.27 * 5.5
c = $6.99
The correct result would be: <span>c = $1.27 * 5.5 pounds = $6.99.</span>
Answer:
Step-by-step explanation:
5s + 6c = 23.91
2s + 7c = 17.89
10s + 12c = 47.82
-10s - 35c = -89.45
-23c = -41.63
c = $1.81 for a large coffee
2s + 7(1.81) = 17.89
2s = 5.22
s = $2.61 for a scone
