Polyethylenimine (PEI) or polyaziridine is a polymer with repeating units composed of the amine group and two carbon aliphatic CH 2 CH 2 spacers. Linear polyethyleneimines contain all secondary amines , in contrast to branched PEIs which contain primary, secondary and tertiary amino groups.
Linear low-density polyethylene (LLDPE) is a substantially linear polymer (polyethylene), with significant numbers of short branches, commonly made by copolymerization of ethylene with longer-chain olefins.
It had an original storage capacity of 9,000,000 m 3 (7,300 acre⋅ft), and was later expanded to 25,000,000 m 3 (20,000 acre⋅ft) during the Linthal 2015 expansion, to hold extra capacity for the new pumped-storage power station. A 2.2 MW solar farm was added to the Muttsee dam in 2021, supplying 3.3 GWh per year. [1]
Variable speed pumps were replaced with two-speed pumps (each rated at 35,400 US gallons per minute (2.23 m 3 /s) for a discharge pressure head of 865 feet (264 m)), and a flow control valve (adjustable from 22% open to 100% open with a linear flow response) was added to each loop for use in regulating recirculation flow (capable of regulating ...
This flight suddenly dropped 26,000 feet, injuring 17 passengers in latest Boeing incident. Kathleen Wong, USA TODAY. Updated June 28, 2024 at 1:31 AM.
Developed by the Argentine National Atomic Energy Commission (CNEA) & INVAP, CAREM is a simplified pressurized water reactor (PWR) designed to have electrical output of 100 MW or 25 MW. It is an integral reactor – the primary system coolant circuit is fully contained within the reactor vessel. The fuel is uranium oxide with an enrichment of 3.4%.
A United Airlines jet headed to Rome turned around less than an hour into the flight and descended rapidly after what the airline termed an indication of possible loss of cabin pressure. The plane ...
The plant has two identical direct cycle turbines of 25 MW each. Each turbine is rated at 6.1 bars inlet pressure and a steam flowrate of 44.5 kg/s. The geothermal reservoir contains two-phase water. [citation needed] The reservoir temperature is 250-300 °C. Proven steam resources of are 172 kg/s.
