4. A 4-stroke, 8 cylinder diesel engine with bore and stroke of 9 inch x 12 inch, respectively and speed of 1000 rpm has a brake mean effective pressure of 165 psi. determine the engine brake horse power
THE ENGINE BRAKE HORSEPOWER
The engine brake horsepower is approximately 170.92 BHP. To calculate the engine brake horsepower (BHP), we can use the following formula:
BHP = (BP x 2 x N) / 33000. Where BP is the brake power in ft-lb/s, N is the engine speed in RPM, and 33000 is a constant.
How to computeFirst, let's calculate the brake power:
BP = (BMEP x L x A x N x NC) / 2Where BMEP is the brake mean effective pressure in psi, L is the stroke length in inches, A is the area of one cylinder in square inches (π/4 x bore^2), and NC is the number of cylinders.Plugging in the given values:A = π/4 x 9^2 = 63.62 in^2NC = 8L = 12 inN = 1000 RPMBMEP = 165 psiBP = (165 x 12 x 63.62 x 1000 x 8) / 2 = 2,822,260 ft-lb/sNow we can calculate the engine brake horsepower:BHP = (BP x 2 x N) / 33000 = (2,822,260 x 2 x 1000) / 33000 = 170.92 BHPFor more information about the engine please open the link: brainly.ph/question/7954831

5. A ball is inflated to a pressure of 356 pounds per square inch (psi). Convert this pressure to atmospheres (atm).
Answer:
24.2244 atm
Explanation:
1 atm is equal to 14.696 psi, so we just divide.
356 psi ÷ 14.696 = 24.2244 atm.
6. When diving in the ocean, you must consider how much pressure you will experience from diving a certain depth. From the atmosphere, we experience about 14.7 pounds per square inch (psi) and for every foot we dive down into the ocean, we experience another 0.44 psi in pressure. How far (in feet) can you dive without experiencing more than 58.7 psi of pressure on your body?
a1 = 14.7 d = 0.44 an = 58.7 n (in foot) = ?
an = a1 + (n-1)(d)
58.7 = 14.7 + (n-1) (0.44)
58.7 = 14.7 - 0.44 + 0.44n
0.44n = 58.7 – (14.7-0.44)
0.44n/0.44 = (58.7- 14.26)/0.44
n = 44.44/0.44
ANSWER: 101 feet.

How far (in feet) can you dive without experiencing more than 58.7 psi of pressure on your body?
arithmetic sequence
common difference is 0.44 psi
a1= 14.7 psi
an= 58.7 psi
an= a1+(n-1)d
58.7=14.7+ ( n-1) 0.44
58.7= 14.7 + 0.44n - 0.44
58.7= 0.44n + 14.26
0.44n= 58.7 - 14.26
0.44n= 44.44
n=101
you can dive in less than 101 ft

How far (in feet) can you dive without experiencing more than 58.7 psi of pressure on your body?
Answer:
8.33 ft.
Step-by-step explanation:
Pressure
Pressure exist underwater because the water is denser than air. Calculation of the pressure for the divers are important because they might feel discomfort if the pressure that their body can carry exceeded to the normal pressure. Different units are used by the divers to define the pressure underwater. From the atmosphere, people has 1, 000 millibars (mb) or 14.7 pounds per square inch (psi) of pressure. Mathematically that is,
1 atmosphere = 1, 000 mb = 14.7 psi
To anwer the question,
Step 1: Let x = depth in feet a diver can dive not exceeding to 58. 7 psi. (This must be multiplied to 0.44 psi because we are determining how much depth will have.)
0. 44 (x)
Step 2 : Make a mathematical sentence. Put 58.7 psi in the left side and equate it to 14.7 psi + 0.44 psi (x).
58. 7 psi = 14.7 psi + 0.44 (x)
Step 3 : Transpose 14.7 psi to the left side of equation and change the sign from + to - . Then subtract 58. 7 psi to 14.7 psi.
58.7 psi - 14.7 psi = 0.44 psi (x)
44 psi = 0.44 psi (x)
Step 4: Divide both sides by 0.44 psi so that x will remain in the right side of equation.
\frac{44 psi}{0.44 psi} = x
0.44psi
44psi
=x
100 = x
Step 5: Since this is measured by inches, convert the unit from inches to feet.
that is, 100 inch = 8.33 ft.
Therefore, a person can dive 8.33 ft. without experiencing more than 58.7 psi of pressure on their body.
