Detailed Solution
Download Solution PDFस्पष्टीकरण:
घर्षण के कारण शीर्ष हानि के लिए डार्सी-वीसबैक सूत्र निम्न है,
\(h_f = \dfrac{4flV^2}{2gd}\)
जहाँ, f = डार्सी का घर्षण गुणांक, l = पाइप की लंबाई, v = पाइप में द्रव का वेग, d = पाइप का व्यास।
From the above, hf ∝ V2
Calculation:
Given:
V1 = V, V2 = 2V
\(\frac{h_1}{h_2}=(\frac{V_1}{V_2})^2\)
\(\frac{h_1}{h_2}=(\frac{V}{2V})^2\)
\(\frac{h_1}{h_2}=\frac14\)
h2 = 4h1
