Question

please give me urgently ans explain how to come this in hindi please​

Answer 1

Answer: OPTION (1)

Thermal Conductivity ka formula hai

H = KA(T₂ - T₁) / L

A - Area ; L - length ; T - temperature ; K - Thermal Conductivity

H - heat rate

K = H*L/(A*(T₂ - T₁))

K = [ML²T⁻³] * [ L] /(L²)*(K)

K = M¹L¹T⁻³K⁻¹

H - heat flow rate hai jiska formula simple tareeke se Q/t se represent karte hain

Uska dimensions hai - {ML²T⁻³}

A - L²

T - K

Toh Formula mai substitute karke, hum yeh formula (dimensional) derive kar sakte hain
