Development of Natural Filling Cystometer and Comparison with Conventional Cystometry
… and abdominal pressures to the digital manometers. The pressures were stored within the portable computer and turned into graphs indicating pressure changes. The NFC is thought to be a physiological test that is affordable and convenient because of its simple structure and small size. …

Some aspects of stratified flow in closed conduits
… tanks, a receiving tank, flow control valves, manometers, and discharge measuring devices, was built for the above investigations. The equation of motion was derived for the velocity distribution, starting from the Navier-Stokes equations. A special Poisson equation with a constant term on the …

An analytical and experimental investigation of the hydraulic transport of high concentration mixed regime slurries
… slurry flow. Pressures are checked with water manometers. The data acquisition system is interfaced to a microcomputer that calculates required. values and outputs tables and graphs of measured values. Detailed observations of the flow conditions are made through clear viewing sections in each …

Flow patterns on distillation trays
… the height of clear liquid across the tray with manometers. The flow rates used were designed to show how the flow pattern changed with the change in the gas and liquid rates. The results from water-only studies on an un-perforated tray were compared with those produced on a sieve tray with holes …

The determination of the operating characteristics of an 18- inch stoneware gas absorption tower
… stream. Orifices, metering central valves, and manometers were installed in all pipe lines conveying materials to the tower in order to increase the ease and accuracy of controlling the flow of these various materials. After the above changes had been completed, a series of nineteen test runs …

The design of a commercial plant for the production of ethylene glycol
… of needle valves and indicated by water filled manometers. The reactant gas mixture was pre-heated prior to passage through the reactor tube. A series of runs was made to determine the effect of ethylene concentration on the oxidation reaction. The temperature was held at approximately 260°C. …

The use of flow control devices to improve the flow pattern and throughput of sieve trays
… across the tray and in the downcomer using manometers. This work presents experiments designed to evaluate flow control devices proposed to improve the gas liquid interaction and hence improve the tray efficiency and throughput. These are (a) the use of intermediate weirs to redirect liquid …
