How many natural gas therms are required to heat a 60 gal water tank from 55F to 140F?
1 therm = 1.05 X 108 joules
1 gallon = 3.79 liters
60 gallons X 3.79 = 227.4 liters
Water = 1g/mL = 1000g/1000mL = 1kg/1L
227.4L = 227.4 kg
Specific heat of water = 4,186 j/kg°C
140°F = 60°C
55°F = 12.78°C
Q = mC∆T
Q1 = (227.4 kg)(4,186 j/kg°C)(60°C - 12.78°C)
Q1 = 4.495 X 107
(4.495 X 107 j)(1 therm/1.05 X 108 j) = 0.428 == ==
What else can I help you with?
What temperature is required to kill bacteria in water?
The temperature required to kill bacteria in water is typically 140F (60C) or higher.
What temperature is required to effectively kill bacteria in water?
The temperature required to effectively kill bacteria in water is typically around 140F (60C) or higher.
Should you set your hot water heater at 140f?
NO! 100-120F setting normal. 140F can cause accidental scalding.
What is the temperature at which bacteria in water are killed?
The temperature at which bacteria in water are typically killed is 140F (60C) or higher.
What temperature of water is effective in killing germs?
Water temperature of at least 140F (60C) is effective in killing germs.
What is the temperature at which water kills bacteria?
The temperature at which water kills bacteria is typically around 140F to 150F (60C to 65C).
What Material melts at 140F?
Paraffin wax
What is the Fahrenheit of 60 degrees Celsius?
60C = 140F
What is the danger zone in the kitchen?
4c-60c (40f-140f)
What is dangerzone?
Cooked food should be maintained either cold or hot and that means either below 40F or above 140F. That makes 40F to 140F the "danger zone" because that's the temperature range where bacteria thrives.
What is 40 degrees and 140 degrees in Celsius?
40f = 4.444444...C 140f = 60c
What is the recommended cooking temperature for ham?
The recommended cooking temperature for ham is 140F (60C).
