Ike Ultrasonic
N'ime usoro mgbasa ozi ụda ụda, mgbe a na-ebufe ụda ụda gaa na ebe a na-akwụ ụgwọ mbụ, ihe ndị ahụ na-emegharị ahụ na-ama jijiji azụ na azụ n'akụkụ ọnọdụ nha anya, na-akpata mkpakọ na mgbasawanye na etiti.

Dị ka mgbasa nke ụda ebili mmiri na-ajụ na-esonyere na mgbasa nke ike, ọ bụrụ na anyị na-ewere a obere olu elementrị (dV) na ụda olu, ka mbụ olu nke na-ajụ na-Vo, nrụgide na-po, na njupụta bụ ρ0. The kinetic energy of the volume element (dV) n'ihi ụda ebili mmiri △Ek; △Ek=(ρ0 Vo)u2/2
△Ek bụ ike ike, J; u bụ urughuru ngwa ngwa, m/s; ρ0 bụ ọkara njupụta, kg/m3; Vo bụ olu izizi, m3.
Akụkụ dị mkpa nke ultrasound bụ ike ya. Superwave nwere ike dị ike karịa ebili mmiri nkịtị. Nke a bụ otu n'ime ihe dị mkpa mere enwere ike iji ultrasound mee ihe n'ọtụtụ ebe.
Mgbe ebili mmiri ultrasonic rutere n'ụdị ụfọdụ, ụmụ irighiri ihe ndị na-emegharị ahụ na-ama jijiji n'ihi omume nke ebili mmiri ultrasonic, na ụda mkpọtụ bụ otu ugboro nke ebili mmiri ultrasonic.
