Momwe mungawerengere mphamvu ya zida zotenthetsera zotenthetsera?

Kuwerengera mphamvu ya zida zotentha P=(C×T×G)÷(0.24×S×η) Ndemanga za zida zotenthetsera:

1.1 C=Kutentha kwapadera (kcal/kg ℃)

1.2 G = kulemera kwa ntchito (kg)

1.3 T=Kutentha kwa kutentha (℃)

1.4 t=nthawi (S)

1.5 η = kutentha bwino (0.6)

2. Kuzimitsa mphamvu yowerengera zida zotenthetsera zolowera P=(1.5—2.5)×S2.1S=malo opangira ntchito kuti azimitsidwa (masentimita apakati)

3. Kuwerengera mphamvu yosungunuka ya zida zotenthetsera zolowetsa P=T/23.1T= mphamvu ya ng’anjo yamagetsi (T)

4. Kuwerengera pafupipafupi kwa zida zotenthetsera zoyambira δ=4500/d24.14500=coefficient

5. d=utali wozungulira
