consider a multiple pump system to meet the design requirements. Two typical options include parallel and series configurations of pumps. Specific performance criteria must be met when considering these options. Given a piping system which has a known design flow rate and head requirements‚ Qdes‚ hdes‚ the following pump selection criteria apply. Pumps in Parallel: Assuming that the pumps are identical‚ each pump must provide the following: Q(pump) = 0.5 Qdes h(pump) = hdes Pumps in Series: Assuming

Through common practise of Centrifugal pump operating characteristics is it possible to determine the optimum conditions of particular conditions. The results of typical characteristics are expressed on this work in terms of pump discharge pressure‚ pump efficiency‚ and power demand at various pump speeds of verses pump discharge.

afflicted with diabetes are at risk for a variety of pathologies resulting in many complications including foot ulceration and amputation. The multi-factorial etiology of diabetic foot ulcers is evidenced by the numerous pathophysiologic pathways that can potentially lead to this disorder. A multicenter study attributed 63 percent of diabetic foot ulcers to the critical triad of peripheral sensory neuropathy‚ deformity‚ and trauma (Reiber‚ et al.‚ 1999). The following discusses the pathophysiology of each

CENTRIFUGAL PUMP A centrifugal pump converts the input power to kinetic energy in the liquid by accelerating the liquid by a revolving device - an impeller. The most common type is the volute pump. Fluid enters the pump through the eye of the impeller which rotates at high speed. The fluid is accelerated radially outward from the pump chasing. A vacuum is created at the impellers eye that continuously draws more fluid into the pump. The energy created by the pump is kinetic energy according the

machinery problem. We intend to do a project on “Vibration analysis of centrifugal pump at BPCL Kochi Refinery”. The vibration analysis we have done is a part of predictive maintenance on rotary equipments. This technique is mainly used for the improved performance of equipments. Using this we can predict the condition of internal parts of the equipment. We are mainly dealing with the vibration analysis of centrifugal pump‚ compressors and motors. It includes typical causes of vibration like misalignment

The use of Diabetic Alert Dogs to manage blood sugar levels in Type 1 Diabetic Children 13‚000 children and adolescents are diagnosed annually with type 1 diabetes. Traditional care and management for this disease includes insulin therapy and blood sugar monitoring. One of the dangers associated with disease is hypoglycemia most commonly referred to as low blood sugar. To date 1 in 3 of the individuals diagnosed with type 1 diabetes will die from an undetected low blood sugar‚ mostly resulting

Centrifugal pump A centrifugal pump is a rotodynamic pump that uses a rotating impeller to increase the pressure of a fluid. Centrifugal pumps are commonly used to move liquids through a piping system. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller‚ flowing radially outward into a diffuser or volute chamber (casing)‚ from where it exits into the downstream piping system.[1][2] Centrifugal pumps are used for large discharge through smaller
