Many area's that use speed bumps to slow traffic will have a law like 'failing to obey traffic control device' or something to that affect. Essentially, they are there to slow you down.
The horizontal component of velocity[Ux] ucosA* 40.3 x cos37* 32.19 m/s Thus the time taken (t) by stream to reach building:- By R [Ux] x t 60 32.19 x t t 1.86 sec The vertical component of velocity[Uy] usinA* 40.3 x sin37* 24.25 m/s Thus the vertical height (h) attained by the stream:- By s ut - 1/2gt^2 h 24.25 x 1.86 - 1/2 x 9.8 x (1.86)^2 h 28.15 m Thus the floor of building to which the steam will reach (n) 28.15/4 7.04 ~7th floor.
Hello Balsaxx, There is so much hype regarding natural gas and copper pipes. Just to give you some peace of mind, Many people will say not to connect copper pipes to natural gas, is what they fail to tell you, is that when all houses were built, the original pipe was made from copper, over the years things in the world of construction have changed, they have found new materials to last longer, have found different fluxes applied to the joints on copper pipes to last longer etc etc. I am 100% British, we have houses that are still standing well over 200 years of age, with the addition of gas central heating and modern heating systems. We never use anything but copper for our plumbing, unless the original house was plumbed using lead pipes. I moved to the USA approximately 5 years ago, and am a self employed contractor, we do anything from installing a light fixture to building a dream custom home. Do not get sucked into the false claims that copper will erode and it is a bad thing, Copper is by far the best choice for any plumbing application, and I am positive that when your house was built, the plumbers knew about all the different types of flux. Flux is used to around the joints, to make the soldier run around the joint and create a water tight or gas seal. I have a house that is 140 years old here, all the pipes are copper and the water is supplied from a well, I have a gas furnace and all the pipes are fine, the well water does build up sediment in the pipes, and one of my bathrooms has a shower which is a bit slow, the water pipes/copper pipes connecting the shower is original I.E. 140 years of age. There are too many people hearing horror stories about copper and gas, copper and water etc. You have nothing to worry about, and if you out live your house than maybe consider a change in about 200 years lol. I hope this gives you peace of mind and do not worry. Paul M
