Nowadays maintenance-free lead-acidbatteries are common in vehicles,inverters, and UPS systems. If thebattery is left in a poor state of charge, itsuseful life is shortened. It also reduces thecapacity and rechargeability of the battery.For older types of batteries, a hygrometercan be used to check the specific gravityof the acid, which, in turn, indicates thecharge condition of the battery. However,you cannot use a hygrometer for sealedtypemaintenance-free batteries. The onlyway to know their charge level is by checkingt ....etc

AIR INDEPENDENT PROPULSION SYSTEM FOR SUBMARINES
ABSTRACT
Air independent propulsion (AIP) system is a term that encompasses technologies, which allow a submarine to operate without the need to surface or use a snorkel to access atmospheric oxygen. The term usually excludes the use of nuclear power, and describes augmentation or replacing the electric propulsion system of nonnuclear vessels. AIP is usually implemented as an auxiliary source. Most such systems generate electricity which in turn drive an electric motor for propulsion or recha ....etc

The Lead Acid Battery
Lead-acid batteries, invented in 1859 by French physicist Gaston Planté, are the oldest type of rechargeable battery. Despite having a very low energy-to-weight ratio and a low energy-to-volume ratio, their ability to supply high surge currents means that the cells maintain a relatively large power-to-weight ratio. These features, along with their low cost, make them attractive for use in motor vehicles to provide the high current required by automobile starter motors.

Thermodynamic Analysis of Compressed Air Vehicle Propulsion



Introduction
The air flow of a compressed air car is schematically shown in Figure 1. The
following two questions need to be answered.
E-Motor Compressor
Schematic of air compression, compressed air transfer to car and
the use of compressed air for vehicle propulsion


Air Compression
Three compression processes are illustrated in a pressure-volume diagram
(Figures 2) and a tempera ....etc

AIR BREATHING PROPULSION
In contrast to a rocket engine which, in addition to the fuel, carries along an oxidizer, an air-breathing propulsion system uses atmospheric air to oxidize the liquid fuel. Air- breathing propulsion systems include the jet engine, the ramjet and the scramjet. The field of air-breathing propulsion involves various disciplines in science and engineering such as fluid dynamics, turbo machinery aerodynamics, thermodynamics, and materials and structures.
