FLOW AND HEAT TRANSFER IN MINIATURE FLOW PASSAGES

Automotive capacitors are rated in microfarads, and the rating is usually stamped on the case. Always choose a capacitor rated for the maximum expected voltage.• DIAGNOSIS / TESTINGCapacitors can be tested for short circuits using an ohmmeter. Connect one test lead to the capacitor mou[r]

Compact heat exchanger surfaces are described in the literature by geometric factorsthat have been standardized largely through the extensive work of Kays and London(1984). These factors and the relationships between them are essential for applicationof the basic heat<[r]
