โฆ Synopsis
THE PURPOSE of this communication is to note briefly the results obtained in a modiiied constant cross-section variablearea flowmeter. DANCKWEIUS and SIKDER [l] have shown earlier the usefulness of the perforated-tube type of flowmeter. Following their suggestion, KEHAT [2] recently described a constant cross-section variable-area flowmeter. In this work Kehat's flowmeter is further modified to obtain a linear relationship between float-height and flow-rate at a higher ratio of the float-height to the tube diameter. This will be convenient when a single instrument is to be used for a considerable range of flow-rates. Apart from this, the discharge coefficients recommended by Kehat for air and water are different from each other. It would be desirable to obtain the same discharge coefficient irrespective of the fluid being used. The modified flowmeter eliminates some of these drawbacks.

Equations of thermal equilibrium along coronal loops are solved in the absence of gravity but where the cross-sectional area changes along the loop. The footpoint temperature is assumed to be 2 x 104 K. Several fundamental types of solution are found, namely hot loops, cool loops, hot-cool loops (wh
