Basic geomentry provides the following: The shape of the roof defines a right triangle with opposite angles being 45 degrees and therefore opposite sides must be equal in length. Knowing this and the basic Pythagorean theorem that a2 + b2 = c2 and a must equal b in our example, yields the substitution of a2 + a2 = c2 cbeing 10 feet in our example yields 2a2 = 100 feet a2 = 50 feet a = SquareRoot of 50 feet a = 7.07 feet Assuming that the horizontal dimension is the larger value (20 feet), the roof has the effective dimension of 7.07 feet by 20 feet or 141.4 square feet. Multiply by 144 (number of square inches per square foot) yields 20,361.6 square inches Mulitply by 1 inch of rainfall per hour yields 20,361.6 cubic inches of rain per hour Divide 20,361.6 by 231 (cubic inches per gallon) yeilds 88.145 gallons per hour Note: This is a theoretical maximum, the actual accumulation will be slightly less due to the amount needed make the roof surface "wet" before runoff begins. Also, rain drops splatter at this rate and there will be a modest loss around the edges of the roof that will reduce the total runoff. At this rate of rainfall, it will take about 11 hours and 21 minutes to collect 1,000 gallons of water.
35 degree Celsius = 95 degree Fahrenheit 35 degree Celsius = 554.67 degree Rankine 35 degree Celsius = 28 degree Reaumur 35 degree Celsius = 308.15 kelvin
Yes. 1 degree of Fahrenheit is 5/9 of a degree Celsius (centigrade)
There is no degree Fahrenheit for heat.
425 degree Fahrenheit = 218.3333333 degree Celsius
17 degree celsius is colder.
Above 100 degree celcius
Assuming that you are using the near obsolete units for measuring temperature, the answer is 180 gallons at 100 degrees Fahrenheit.
That all depends on what you want the final temperature of the mixture to be. Technically, one single drop of 40-degree water will reduce the temperature of the 800 gallons.
Suppose G gallons are used. Before mixing, you have 5*65 + G*120 = 325 + 120G gallon-degrees. After mixing, you have (5+G)*70 gallon-degrees So 325 + 120G = (5+G)*70 = 350 + 70G So 50G = 25 G = 0.5 gallons.
1 imperial gallon is about 4.5 liters (to an absurd degree of detail = 4.54609188 litres). To convert a value in imperial gallons to litres, multiply by 0.22 or 0.219969248299.1 US gallon is about 3.8 liters (to an absurd degree of detail = 3.78541178 liters)(isn't it stupid to have two different gallons?)
how hot is the boiling water? That makes a big difference? (is that a homework question?) I'm just trying to apply logic here, bear in mind there may be some special properties that you may have to account for like the glass/plexiglas that the water is in will have to have its temp raised also. So here goes... Raising 500 gallons of water 20 degrees would seem to require a combined value of 10,000 degrees (500 gallons times 20 degrees). So first you need to know the temperature difference between the existing water and boiling. Then devide the resulting difference into the 10,000 degrees for your simplistic answer. However, it is a bit more complicated if the tank is full at 500 gallons because you have no room to add the boiling water. That is, it would roughly take 62 gallons of boiling water to raise 500 gallons of 50 degree water to 70 degrees and the tankwouyld obviously overflow. So if it was already full you would have had to remove 62 gallons first leaving 438 gallons and consequently reducing your degree needs to 8760 degrees which means if you add the 62 gallons of boiling water you would have ended up with 72.7 degree water. So, I'd reduce the capacity to 445 gallons and add 55 gallons of boiling water and you should be pretty close.
First find out how many moles of gas are collected under the given conditions using the Ideal Gas Law.See the Related Questions link to the left for how to do that. Then use that number of moles and determine the volume of that much gas at STP, also using the Ideal Gas Law question to the left.
The water temperature of the San Francisco bay is averaging from mid 50's to low 60 degree's.

Even a single drop of water will dilute 28 ppm of cyanide. Not by much, perhaps, but the question does not specify dilution to what degree.
280,000 gallons * 16 pounds per gallon = 4,480,000 pounds of water 1 BTU to raise 1 pound of water 1 degree F (at 60 to 61, Standard Atmospheric Pressure) 1 pound of propane ~ 22,000 BTU 4,480,000 / 22,000 ~ 203 203 pounds of propane ~ 50 gallons Burning approx 50 gallons of propane will heat 280,000 gallons of water by one degree. (Hardly a geothermal event, they burn more propane in the average tailgate at a NFL game.)
This all depends on the temperature outside or in the chicken coop. Eggs left in relatively cool temperatures (35F to 60F ) can be collected once per day but in temperatures over 75 degree's they should be collected twice per day to ensure safety. Egg store at 36F will last for many weeks in the refrigerator.
