Explain the working principles of a rotary engine​

Engineering
1 answer:
Brut [27]3 years ago
7 0

Answer:

The rotary engine works on the same basic principle as the piston engine: combustion in the power plant releases energy to power the vehicle. However, the delivery system in the rotary engine is wholly unique. The piston engine performs four key operations: intake, compression, combustion, and exhaust.

How many kg / day of NaOH must be added to neutralize a waste stream generated by an industry producing 90,800 kg / day of sulfu
hram777 [196]

Answer:

74.12kg/day

Explanation:

Equation of reaction for the neutralization reaction of sodium hydroxide and sulfuric acid: 2NaOH + H2SO4 yields Na2SO4 + 2H2O

Mass of sulfuric acid produced per day = 90,800kg

Percentage of sulfuric acid in wastewater = 0.1%

Mass of sulfuric acid that ends up in wastewater per day = 0.1/100 × 90,800 = 90.8kg

From the equation of reaction, 2 moles of NaOH (80kg of NaOH) is required to neutralize 1 mole of H2SO4 (98kg of H2SO4)

80kg of NaOH is required to neutralize 98kg of sulfuric acid

90.8kg of sulfuric acid would be neutralized by (90.8×80)/98kg of NaOH = 74.14kg/day of NaOH

alexdok [17]

Answer:

import java.util.Scanner;

public class SumVectorElements

{

public static void main(String[] args)

{

final int NUM_VALS = 4;

int[] origList = new int[NUM_VALS];

int[] offsetAmount = new int[NUM_VALS];

int i = 0;

origList[0] = 40;

origList[1] = 50;

origList[2] = 60;

origList[3] = 70;

offsetAmount[0] = 5;

offsetAmount[1] = 7;

offsetAmount[2] = 3;

offsetAmount[3] = 0;

/* Your solution goes here */

// Print the Sum of each element in the origList

// with the corresponding value in the

// offsetAmount.

for (i = 0; i < NUM_VALS; i++)

{

System.out.print((origList[i] + offsetAmount[i])+" ");

}

System.out.println("");

return;

}

}
