Important Points

- केशाकर्षण म्हणजे नलिका किंवा शोषक सामग्रीमधील द्रव पृष्ठभागाच्या तणावामुळे वर येण्याची किंवा खाली जाण्याची प्रवृत्ती होय.
- वक्र द्रव-वायु आंतरपृष्ठामध्ये दाबाच्या फरकाचा एक परिणाम म्हणजे गुरुत्वाकर्षण असूनही अरुंद नलिकेमध्ये पाणी वर येते हा एक सर्वज्ञात परिणाम आहे.
- केरोसीन आणि वात यांच्यातील एकसंध बल केरोसीनच्या आसंगी बलाच्या तुलनेत जास्त आहे, त्यामुळे केशाकर्षणामुळे केरोसीन वातीमधून वर येते.
- केशाकर्षण कार्यासाठी, नलिकेचा व्यास खूप लहान असला पाहिजे.
- पृष्ठताणामुळे केशाकर्षण नलिकेत द्रव वर जातो.
