At the outlet of a fire hose pressure should be minimum 448 kPa. Length of the hose is 76,2 m, diameter 102 mm and surface roughness 0,8 mm. Water temperature is 16 °C and volumetric flow rate is 0,032 m3/s. What should be the inlet pressure at firetruck to fulfill the pressure requirement at the outlet? Water density is 1000 kg/m3 and viscosity 1003 · 10-6 kg/ms. Round off your answer to one decimal digit in kPa, but enter the answer without the unit.

Calculate pressure loss in a pipe ( d = 55 mm, L = 200 m ), for oil mass flow rate of 133 kg/min. Oil density is 900 kg/m3and kinematic viscosity is ν = 4·10-5 m2/s. The sum of local losses in the pipe is 3,5. Round off the answer to one decimal digit in kPa, but enter the answer without the unit.

Consider an oil flow of 13 m3/h in a long, straight and smooth pipe with diameter of 6 cm. What is the pressure loss per meter? Oil absolute viscosity is 0,1 kg/ms and density is 900 kg/m3. Friction factor for laminar flow can be calculated fromf=64Re f = \frac{64}{Re} .Round off the answer to an integer in Pa/m, but enter the answer without the unit.

Section A: Read the text and answer the questions. Brutalism is an architectural style, introduced in the 1950s. It uses exposed concrete to create geometric structures with a grey appearance. Concrete buildings are often criticised as cold and ugly, lacking the warmth of stone or the smooth feel of steel. However, concrete, as a building material, has unique characteristics. It is extremely flexible when wet, and is adapted to create interesting shapes. Many urban public buildings, such as universities, have also used concrete as the main material to indicate strength and permanence. Instead of keeping Brutalist buildings, many are being demolished to make space for modern styles. However, this does not acknowledge the cultural history of these buildings, and is not sustainable. Fill in the gap with ONE WORD from the paragraph. 1. Brutalist architecture included exposed concrete, which gave a cold Answer Question 1[input] .
