The London, Tilbury and Southend Railway (LTSR) 79 Class is a class of 4-4-2T suburban tank engines. They were designed by Thomas Whitelegg, as a development of the earlier 37 Class. They could reach a top speed of 65 mph (105 km/h). [1]
Ultra-high temperature processing (UHT), ultra-heat treatment, or ultra-pasteurization [1] is a food processing technology that sterilizes liquid food by heating it above 140 °C (284 °F) – the temperature required to kill bacterial endospores – for two to five seconds. [2]
Solar heat is clean and renewable. This is the most modern system. Increasingly, solar powered water heaters are being used. Their solar thermal collectors are installed outside dwellings, typically on the roof or walls or nearby, and the potable hot water storage tank is typically a pre-existing or new conventional water heater, or a water heater specifically designed for solar thermal.
If the storage tank of an electric heater is highly insulated, so that the outer surface of the tank is only slightly warmer than the ambient air, the savings with a tankless heater is less. Savings in water use: Users in remote points in the building do not have to run the hot water as long, waiting for it to get to the faucet.
A bulk milk cooling tank is a storage tank located in a dairy farm's milkhouse used for cooling and holding fluid milk at a low temperature until it can be picked up by a milk hauler. Since milk leaves the udder at approximately 35 °C, milk tanks are needed to rapidly cool fresh raw milk to a storage temperature of 4 °C to 6 °C, thereby ...
Hot water tanks may have a built-in gas or oil burner system, electric immersion heaters. Some types use an external heat exchanger such as a central heating system, or heated water from another energy source. The most typical, in the domestic context, is a fossil-fuel burner, electric immersion elements, or a district heating scheme. [2]
An 80 US gal (300 L; 67 imp gal) electric storage tank water heater was able to have a minimum energy factor of 86% under the pre-2015 standard, while under the 2015 standard, the minimum energy factor for an 80-gallon electric storage tank water heater is now 197%, which is only possible with heat pump technology. This rating measures ...
The main armament of the 2S25 is a 125 mm smoothbore 2A75 tank gun, which is a derivative of the 125 mm 2A46 tank gun. [13] The angles of elevation and depression for the anti-tank gun are +15° and −5° respectively. When aimed towards the stern of the vehicle, the elevation and depression of the gun changes to +17° and −3° respectively. [4]
