PIPE VALVES FITTINGS i2*9-1323 FlushlnK Ave, Brooidyn, more than 500 square foot of radiation. A fairly accurate method for deter- mining the amount of radiation that shouhl be carried by a main of a certain size is to take one-tenth of the square root of the number of square feet ot radiation to be carried as tlie diameter in inches of the supply or feed pipe, for a low pressure steam system. Thus a 2-inch supply pipe should carry as a maximum 400 square feet. With more than 500 square feet in the present sys- tem, it will be seen that it is more than should be carried by a 2-inch feed. If the proposed extension is made to the longer house, this will add forty- five feet to the length of the system coil or about 100 square feet of radiation. To correct this difficulty, it is suggested that the present steam main be used only to supply the steam coils in the frame and in the 75-foot house, discon- necting the other coil. To heat the steam coil in what will be the 150-foot house, we should run another 2-inch feed pipe to the north end of this house and there Healthy Plants Even, dependable heat is the keystone of successful growing. Your plants must have the temperature best suited to their natural growth. And that, heat must be uniform.
