Essays on Water Pump

The Ghost Map, by Steven Johnson, is a narrative that revealed how diseases spread, how cities developed and how people viewed science in 1854. Integrative thinking and the ability to make connections enabled Dr. John Snow to trace the pattern of the disease to its origin. John’s ability to make a connection between the epidemic and the water the people consumed was marvelous. It enabled him to save people’s lives. It is, therefore, important to have an open mind and think in a connective manner. This is a narrative that took place in 1854 during summer. London, ...

BERNOULLI’S EXPERIMENT

ABSTRACT Two fluid properties, the Bernoulli principle and the Venturi effect, were examined and analyzed in this experiment. A venturi meter was used to measure the fluid flow rate, velocity, and pressure of water (the fluid being examined). The results showed that the fluid pressure decreases as the fluid traveled through a smaller cross sectional area. The minimum fluid pressure (in effect, maximum fluid velocity) was observed in the smallest cross sectional area at position D (diameter 16 mm). The decrease in fluid pressure was compensated by an increase in the fluid velocity. With these two measured phenomena, both ...

Helen Keller’s The Story of My life

They Story of My Life is an autobiography written by Helen Keller, the first deafblind person to earn a bachelor’s degree in arts. Her educational achievement is even more notorious considering that at the beginning of the twentieth century women had limited educational and work opportunities. At 22 and while still a student at Radcliffe College she published her autobiography, The Story of My Life, which had appeared the year before in installment form in the Ladies Home Journal magazine.1 Helen Keller opened the doors to education and opportunity to many blind and disabled people not only in ...

Pump Application: Building Water Pump

Pumps are devices used to move fluids from one point to another by creating differences in pressure between the two points. Pumps are powered by a prime mover, which can be either a diesel engine or an electric motor. The pump converts the energy supplied by the prime mover to potential energy by pressurizing the fluid it’s pumping. For example, a diesel pump has an engine that converts chemical energy in the fuel to mechanical energy in the form of torque. The torque from the engine is then picked up and transmitted to the pumping mechanism for fluid ...

Introduction

Pumps installed in fire engines either hoses out water from the fire tanker or suck water from a source such as fire hydrants, lakes, or pools. Different mechanisms control the pumping of water from a water source to the scene of the fire. Usually, a 6 inch suction pipe is used to extract water out of the water tank or an external water source. The water is then discharged out through exit lines or hoses with a certain force to eventually quench the fire.

The Impeller Pump

The main source that pumps water is the impeller water pump. This is a propeller type device that has curved ...
