The inventor of a water wheel claims that his design is better than a conventional overshot or breast wheel at extracting energy from water flows at low heads. He states that the design shown can generate up to 260 W of power from a head of 0.8 m. average household energy use over a 24-hour...
Workings so far...
(i) the mass of the roller
density = 7860 kg/m³
OD = 0.3 m ID = 0.2 m
Length = 1.2 m
Surface area of end section = OD – ID
= π0.3² - π0.2 ²
= 0.283 – 0.126
= 0.157
Volume = π r² h
= 0.157 x 1.2
= 0.1884 m³
Mass = Density x Volume
Mass =...
Can you tell me how to add my workings to this questions please? Also I can't see how I added this thread, there is no simple "add thread" option, I just found it somehow last time. Thanks.
Any help you can give me on the following question?
(a) A heavy industrial mill roller gets loose and rolls down a slope without slipping or sliding. It drops in height 900 mm. it is made of steel and is a hollow cylinder of outer diameter 600 mm, inner diameter 400 mm and length 1.2 m...
