The question states that one 4-inch 

 flow and twenty-eight 2-inch returns 

 are used to heat a house 42x150 feet. 

 From this it will be seen that the 4- 

 inch flow has to supply about 2,200 

 square feet of radiating surface; also 

 that there is the equivalent of thirty 

 2-ineh pipes in a house forty-two feet 

 wide, which would be suflScient to heat 

 the house to 63 degrees if the piping is 

 properly arranged.
