Manometer chubhu - matambudziko nemhinduro

Manometer chubhu - matambudziko nemhinduro

1. A chubhu yemanometer izere nemhando mbiri dzemvura. kuwanda yemvura 1 ndiyo ρ1 = 0.8 g.cm-3, uye huwandu hwemvura 2 ndi ρ2 = 1 g.cm-3, uye kukwirira h1 = 10 cm, saka kukwirira kwe h chii?2.

Zvinozivikanwa:Chubhu yeManometer - matambudziko nemhinduro 1

Kuwanda kwemvura 1 = 0.8 g.cm-3

Kuwanda kwemvura 2 = 1 g.cm-3

Kureba 1 = 10 cm

Kuda: Kureba 2

Solution:

Chubhu yeManometer - matambudziko nemhinduro 2

2. Kureba kwemvura ndeye 50 cm, uye kukwirira kwezvimwe zvinwiwa ndeye 30 cm. Kuwanda kwezvimwe zvinwiwa kwakawanda sei?

Zvinozivikanwa:

Kuwedzera nekuda kwegiravhiti (g) = 10 m/s2Chubhu yeManometer - matambudziko nemhinduro 3

Kureba kwemvura (h)1) = 50 cm

Kuwanda kwemvura (ρ)1) = 1.00 x 103 kg / m3 = 1000 kg / m3

Kureba kwechimwe chinwiwa (h)2) = 30 cm

Zvaidiwa: Kuwanda kwechimwe chinwiwa.

Solution:

pa + ρ1 gh1 = pa + ρ2 gh2

Chubhu yeManometer - matambudziko nemhinduro 4

  1. Chii chinonzi manometer? mhinduro: Manometer mudziyo unoshandiswa kuyera kumanikidzwa kwemagasi nezvinwiwa. Kazhinji unoyera musiyano wekumanikidzwa pakati pemvura iri mukati memanometer nemhepo yakapoteredza kana imwe mvura.
  2. Ko U-tube manometer iri nyore inoshanda sei? mhinduro: Manometer yeU-tube inoshanda zvichibva pakuenzanisa kumanikidzwa kunoitwa nekoramu yemvura nechisimba chemvura iri kuyerwa. Kana paine musiyano mukumanikidzwa, koramu yemvura ichaenda panzvimbo itsva, uye musiyano wekukwirira unogona kushandiswa kuona musiyano wekumanikidzwa.
  3. Ndezvipi zvinwiwa zvinoshandiswa mumanometers? mhinduro: Zvinoshandiswa pakuongorora mvura zvinosanganisirwa nemercury, mvura, nemafuta. Sarudzo yezvinonwiwa zvinoenderana nekushandiswa, kunzwisisika kwechinhu, uye huwandu hwezvinomanikidzwa zvinofanira kuyerwa.
  4. Sei mercury ichiwanzo shandiswa muma manometers pasinei nekuti ine chepfu? mhinduro: Mercury yakakora uye ine huremu hwakanyanya, izvo zvinoita kuti pave nekureba kwemakoramu mapfupi uye magadzirirwo madiki emanometer ane musiyano wakafanana wekumanikidzwa. Hainyorovesewo magirazi, zvichiita kuti kuverenga kuve kwakarurama. Zvisinei, hunhu hwayo hune chepfu hunoda kubatwa nekungwarira uye kufunga nezvekuchengetedzwa kwezvakatipoteredza.
  5. Ndeupi musiyano uripo pakati pemanometer akavhurika nemanometer akavharika? mhinduro: Manometer yakavhurika ine mugumo wakavhurika kune mhepo, uye inoyera musiyano wekumanikidzwa pakati pemvura iri kuyedzwa nekumanikidzwa kwemhepo. Manometer yakavharika, kune rumwe rutivi, ine mugumo wakavharika, kazhinji ne vacuum kana kumanikidzwa kunozivikanwa, uye inoyera kumanikidzwa kwakakwana kwemvura.
  6. Manometer ingashandiswa sei kuyera velocity? mhinduro: Uchishandisa musimboti weBernoulli's equation nePitot-static tube, dynamic pressure (ine chekuita nevelocity) uye static pressure inogona kuyerwa. Musiyano wekukwirira mumanometer unoenderana nedynamic pressure, iyo inogona kushandurwa kuita velocity.
  7. Sei zvichikosha kuti chubhu yemanometer ive yakamira panguva yekuyerwa? mhinduro: Kuchengeta chubhu yemanometer yakamira kunoita kuti huremu hwemanometric fluid hushande zvakananga pasi, uye kukwirira kwekoramu yemvura kunomiririra zvakananga musiyano wekumanikidzwa. Chero kurereka kunogona kukonzera zvikanganiso mukuverenga.
  8. Ko differential manometer yakasiyana sei neU-tube manometer iri nyore? mhinduro: Differential manometer yakagadzirirwa kuyera musiyano wekumanikidzwa pakati pemapoinzi maviri mu fluid system, nepo U-tube manometer iri nyore inowanzo yera musiyano wekumanikidzwa pakati pe fluid nemhepo.
  9. Ndezvipi zvinogumira pakushandisa manometer? mhinduro: Manometers zvishandiso zvinoenderana negiravhiti, saka zvinofanira kuramba zvakamira. Zvingave zvisina kukodzera kuyera kumanikidzwa kwakanyanya (zvichienderana nemvura inoshandiswa), uye zvinogona kugadzikana nekuchinja kwetembiricha kunogona kukanganisa kuwanda kwemvura.

  10. Chii chinonzi manometer "yemhando yakanaka"? mhinduro: Manometer yemhando yetsime ine gumbo rimwe rine dhayamita yakakura inonzi "tsime." Mvura iri mutsime iri haikwire kana kudonha zvakanyanya kana paine shanduko dzekumanikidzwa, zvichiita kuti kuverenga kutarisire chete pakuchinja kwehurefu hwegumbo rakatetepa. Dhizaini iyi inowedzera kunzwa uye kuverenga kwemanometer.
