Answer:

Raise =  1391.85\mu F

Explanation:

Given

Temperature = 20^{\circ} F

Gas = 30ft^3

Efficiency = 90\%

Required

Determine the pounds of water

1031BTU = 1ft^3 of water

1\mu F = 20BTU - The energy to raise 1 pound of water by 20F

The raise in pounds is then calculated as:

Raise = Efficiency * Energy * Volume(gas) *  cubic\ of\ water

This gives:

Raise = 90\%* \frac{1\mu F}{20BTU} * 30ft^3 *  \frac{1031BTU}{1ft^3}

Raise = 90\%* \frac{1\mu F}{20BTU} * 30 *  \frac{1031BTU}{1}

Raise = 90\%* \frac{1\mu F}{20} * 30 *  \frac{1031}{1}

Raise = 90\%* \frac{1\mu F}{20} * 30 *  1031

Raise = 90\%* \frac{1\mu F}{20} * 30930

Raise = 90\%* 1\mu F * 1546.5

Raise = 1\mu F * 1391.85

Raise =  1391.85\mu F

Can a mixed Mexican be Chicano ?
yanalaym [24]
A mixed mexican can be Chicano. But term Chicano is normally used to refer to someone born in the United States to Mexican parents or grandparents and is considered a synonym of Mexican-American. A person who was born in Mexico and came to the United States as an adult would refer to him/herself as Mexican, not Chicano.
