Ka taea te wehea te kapohau tauhohenga ki Francis turbine, axial turbine, diagonal turbine me tubular turbine. I roto i te kapohau Francis, ka rere te wai ki roto i te tikanga arataki wai, ka puta mai i te omaoma; I roto i te turbine rere axial, ka rere te wai ki roto i te arataki arataki, ki roto, ki waho hoki o te kaikawe axial; I roto i te turbine rere hauroki, ka rere te wai ki roto i te arataki arataki me te kaikawe i te huarahi e anga ana ki tetahi koki o te rakau matua, ki roto ranei i te arataki arataki me te kaikawe i te huarahi e anga ana ki te rakau matua; I roto i te turbine tubular, ka rere te wai ki roto i te arataki arataki me te kaikawe i te huarahi axial. Ka taea hoki te wehea te turbine rere axial, turbine tubular me te hauroki rere ki te momo propeller me te momo propeller hurihuri kia rite ki o raatau hanganga. Ka mau nga mata o te kaikawe hoe; Ka taea e te mata rotor o te momo propeller te huri huri noa i te rakau mata i te wa e mahi ana ki te urutau ki nga huringa o te upoko wai me te utaina.
He maha nga momo kapohiko tauhohenga he taputapu whakauru wai. Ko nga taputapu uru wai o nga kapohiko tauhohenga poutū poutū nui me te reo-rahi he mea tito he volute, he arataki mau me te arataki nekeneke. Ko te mahi a te volute he tohatoha i te rere o te wai huri noa i te kaihoroi. Ina kei raro te upoko o te wai i te 40m, ko te nuinga o te wa ka makahia te keehi torino o te miihini hiko hiko e te raima whakakaha i runga i te waahi; I te teitei ake o te upoko wai i te 40m, ka whakamahia te kee torino whakarewa o te reke weriweri, te whakarewatanga whakauru ranei.
I roto i te hurihanga tauhohenga, ka whakakiia e te rere o te wai te hongere omaoma katoa, a ko nga matatahi katoa ka pa ki te rere o te wai i te wa kotahi. No reira, i raro i te upoko kotahi, he iti ake te diameter o te kaihoroi i to te turbine impulse. He teitei ake ano to ratou kaha ki tera o te turbine impulse, engari ka huri te kawenga, ka pa te kaha o te turbine ki nga nekehanga rereke.
Ko nga turbine tauhohenga katoa he mea whakauru ki nga ngongo hukihuki, ka whakamahia hei whakaora i te kaha o te rere o te wai i te putanga o te kaihoroi; Tukua te wai ki raro; Ina teitei ake te turanga whakaurunga o te kaihoroi i te taumata o te wai whakararo, ka hurihia tenei kaha kaha ki te kaha pehanga mo te whakaora. Mo te turbine hydraulic me te upoko iti me te rere nui, he ahua nui te kaha o te hiko o te kaikawe o te kaikawe, a, ko te mahi whakaora o te ngongo tauira he nui te paanga ki te pai o te hiko hiko.
