The vent fan will be able to overcome the total head or weight of air in a building chimney. On 2021-01-01 by violeta I replace my hot water tank with an 'on demand' system. The vent which belonged to the hot water tank is now used to vent the bathroom fan. The vent pipe ...
Aircraft approach category means a grouping of aircraft based on a speed of VREF, if specified, or if VREFis not specified, 1.3VSOat the maximum certificated weight. VSO, and the maximum certificated landing weight are those values as established for the aircraft by the certification authority of...
which led to many weeks of lectures and restrictions for the boy. As his parents point out, with the raised bar, “anything more than a kiss, and he doesn’t go.” While I reacted to the kiss with nothing more than a raised eyebrow, I have instructed my daughter (who is not...
These problems pertain particularly to cases in which the species to be implanted has a low atomic weight (such as Boron), so that the acceleration voltage must be small, which translates into a small ion beam flux and a long implant time. For higher atomic weight species (such as Arsenic...
Here, for each instance, the edge weight of an edge 𝑒𝑖𝑗 connecting vertices 𝑣𝑖 and 𝑣𝑗 is represented by (i) uncertain travel cost 𝜉𝑐𝑖𝑗 and (ii) uncertain travel time 𝜉𝑡𝑖𝑗, which are considered as zigzag uncertain variables. In addition, 𝜉𝑐𝑖...
