సరైన సమాధానం ఎంపిక 2) అంటే m2/s.

నిబంధన:

  • గతిశాస్త్ర స్నిగ్ధత: గురుత్వాకర్షణ బలాల ప్రభావంతో ద్రవం యొక్క అంతర్గత ప్రవాహ నిరోధకతను కొలిచేది గతిశాస్త్ర స్నిగ్ధత.
    • ఇది డైనమిక్ స్నిగ్ధతకు ద్రవం యొక్క ద్రవ్యరాశి సాంద్రతకు నిష్పత్తి.
  • డైనమిక్ స్నిగ్ధత: ద్రవం ప్రవహించేలా చేసే బలానికి వ్యతిరేకంగా ద్రవంలో అభివృద్ధి చెందుతున్న అంతర్గత నిరోధకతను కొలిచేది ఇది.
    • దీని SI యూనిట్ పాస్కల్-సెకన్లు.
  • ద్రవ్యరాశి సాంద్రత: ద్రవం యొక్క ద్రవ్యరాశికి ద్రవం యొక్క ఘనపరిమాణానికి నిష్పత్తి. దీని SI యూనిట్ kg/m3.

వివరణ:

  • గతిశాస్త్ర స్నిగ్ధత డైనమిక్ స్నిగ్ధతకు ద్రవ్యరాశి సాంద్రతకు నిష్పత్తి.

కాబట్టి, గతిశాస్త్ర స్నిగ్ధత యొక్క యూనిట్ =

Additional Information 

  • m/s అనేది ప్రవహించే ద్రవం యొక్క వేగం లేదా వేగం యొక్క SI యూనిట్.
  • m3/s అనేది ద్రవం యొక్క ప్రవాహ రేటు లేదా విడుదల రేటు యొక్క SI యూనిట్.

Important Points 

  • గతిశాస్త్ర స్నిగ్ధత తరచుగా C.G.S వ్యవస్థలో పాయిస్ గా వ్యక్తీకరించబడుతుంది.
  • 1 పాయిస్ = 10-4 m2/s.
  • గతిశాస్త్ర మరియు డైనమిక్ స్నిగ్ధత మధ్య తేడా ఏమిటంటే, డైనమిక్ స్నిగ్ధత అనేది ద్రవాన్ని నిర్దిష్ట రేటుతో ప్రవహించేలా చేయడానికి అవసరమైన బలాన్ని కొలిచేది, అయితే గతిశాస్త్ర స్నిగ్ధత అనేది నిర్దిష్ట బలం ప్రభావంతో ద్రవం ప్రవహించే రేటును కొలిచేది.
