Strangely enough, the most complex building to design is the common house. I know, they’re like belly buttons, even if you don’t have one yourself, you know someone that has one, and you’ve certainly been in one.
A house has all the ingredients that you will find in far more complex buildings. On top of that, they are there in small quantities.
Nearly every house has a kitchen, bathroom, laundry and toilet. You will also find some of these in hospitals, hotels, parking stations, office blocks, sewerage works, defence facilities and so on.
The only difference is that in a house, there may only be one of these and it must be the right size, shape and position so that it is suitable for use. Even the doorways must be positioned correctly - to allow for ventilation, light, privacy , ease of access, safety and even feng-shui.
Each room must be the right size for its’ occupants and its’ usage. Bedrooms should have a window or some other method of providing natural light. Toilets and bathrooms should allow for privacy.
The materials that it is built of should be fit for purpose. The roof should provide shelter from the elements. The walls should be able to support the weight of the roof and provide shelter and security for the occupants. The floor should be stable and strong and able to support the activities that are carried out in the house.
On top of all that, it must look good - to somebody. It also must be comfortable to live in, otherwise the design is a fail. That doesn’t mean that it shouldn’t be cheap to build. A good designer designs with one eye on the asthetics, the other eye on the usage and utility and his hand firmly closed around the cheque-book.
Answer:
(a) The maximum volume flow rate for which the flow will be laminar is 0.0190 cubic meter per second
(b) The pressure drop required to deliver the maximum flow rate is 148962.96 Pascal
(c) The corresponding wall shear stress is 7600 Pascal
Explanation:
Reynolds number = 2299, density of water = 1000kg/m^3, diameter of needle = 0.27mm = 0.00027m, Length of needle = 50mm = 0.05m, viscosity of water = 0.00089kg/ms, area = 0.05m × 0.05m = 0.0025m^2, coefficient of friction = 64 ÷ Reynolds number = 64 ÷ 2299 = 0.028
Velocity = (Reynolds number × viscosity) ÷ (density × diameter) = (2299 × 0.00089) ÷ (1000 × 0.00027) = 2.046 ÷ 0.27 = 7.58m/s
(a) Maximum volume flow rate = velocity × area of needle = 7.58 × 0.0025 = 0.0190 cubic meter per second
(b) Pressure drop = ( coefficient of friction × length × density × velocity^2) ÷ (2 × diameter) = (0.028 × 0.05 × 1000 × 7.58^2) ÷ (2 × 0.00027) = 80.44 ÷ 0.00054 = 148962.96 Pascal
(c) Wall shear stress = (density × volume flow rate) ÷ area = (1000 × 0.0190) ÷ 0.0025 = 7600 Pascal
Basically, the purposes of digital multimeter are to measure two or more electrical values such as:
principally voltage (volts)
current (Ampere)
resistance (Ohms)
Answer:
The model was against religous teachings.
Explanation:
Independent auto lots usually have <u>higher</u> finance rates than dealerships
<u>Explanation:</u>
The finance rates that are charged by the dealers are lower than the finance charges that are charged by the independent auto. In case if you are getting financed through dealerships, you can also negotiate with them to charge finance rates and lower the charges of the finance.
But this negotiation and lowering of the finance rates is not possible with the independent auto lots and thus they charge higher rates compared to the dealerships.
