To find how much energy a 5 horsepower (hp) motor delivers in 2 hours, we first need to convert horsepower to watts and then calculate the energy in megajoules (MJ).<\/p>\n\n\n\n
Step 1: Convert horsepower to watts<\/h3>\n\n\n\n
1 horsepower (hp) is equal to 745.7 watts (W). Therefore, a 5 hp motor delivers:5\u2009hp\u00d7745.7\u2009W\/hp=3728.5\u2009W5 \\, \\text{hp} \\times 745.7 \\, \\text{W\/hp} = 3728.5 \\, \\text{W}5hp\u00d7745.7W\/hp=3728.5W<\/p>\n\n\n\n
Step 2: Calculate the total energy delivered in 2 hours<\/h3>\n\n\n\n
The energy delivered by the motor is given by the formula:Energy (J)=Power (W)\u00d7Time (s)\\text{Energy (J)} = \\text{Power (W)} \\times \\text{Time (s)}Energy (J)=Power (W)\u00d7Time (s)<\/p>\n\n\n\n
We need to convert the time to seconds. There are 3600 seconds in an hour, so in 2 hours:2\u2009hours=2\u00d73600\u2009seconds=7200\u2009seconds2 \\, \\text{hours} = 2 \\times 3600 \\, \\text{seconds} = 7200 \\, \\text{seconds}2hours=2\u00d73600seconds=7200seconds<\/p>\n\n\n\n
Now we can calculate the total energy:Energy (J)=3728.5\u2009W\u00d77200\u2009s=26,821,200\u2009J\\text{Energy (J)} = 3728.5 \\, \\text{W} \\times 7200 \\, \\text{s} = 26,821,200 \\, \\text{J}Energy (J)=3728.5W\u00d77200s=26,821,200J<\/p>\n\n\n\n
Step 3: Convert joules to megajoules<\/h3>\n\n\n\n
1 megajoule (MJ) is equal to 1,000,000 joules. So to convert the energy from joules to megajoules:Energy (MJ)=26,821,200\u2009J1,000,000=26.82\u2009MJ\\text{Energy (MJ)} = \\frac{26,821,200 \\, \\text{J}}{1,000,000} = 26.82 \\, \\text{MJ}Energy (MJ)=1,000,00026,821,200J\u200b=26.82MJ<\/p>\n\n\n\n
Final Answer:<\/h3>\n\n\n\n
The 5 hp motor delivers 26.82 MJ<\/strong> of energy in 2 hours.<\/p>\n\n\n\n How much energy does a 5hp motor deliver in 2 hours. Answer should be in MJ The Correct Answer and Explanation is: To find how much energy a 5 horsepower (hp) motor delivers in 2 hours, we first need to convert horsepower to watts and then calculate the energy in megajoules (MJ).
