The diameter of spray nozzle and pressure of sprinkler in the front of the spray nozzle are the major factor that affects sprinkler range.
而喷嘴前的水流压力和喷嘴直径则是影响喷头射程的主要因素。
Normally, the diameter of this hole can range between 1/2 and 5/8 depending on the type of sprinkler tubing being used.
通常情况下，这个直径洞的范围可以从1 / 2和5 / 8取决于管材型喷头使用。
Experimental results also indicated that sprinkler uniformity had little effect on crop yield for the studied range of CU.
试验结果还表明，在所研究的喷灌均匀系数范围内，均匀系数对产量的影响不明显。
