What thickness is 20 gauge in MM? 0.9mm How do you determine shell thickness? The shell thickness excluding corrosion allowance (t) is the highest of the thickness amongst tc, tl, tu: t=max(tc,tl,tu) (6)¶MAWPc=SEtR+0.6t. (7)¶MAWPc=SEloge(R+tR) (8)¶MAWPl=2SEtR−0.4t. (9)¶MAWPl=SE(Z−1) MAWP=min(MAWPc,MAWPl) Vm=πS(R2o−R2) How do you determine the thickness of a reactor? hoop-stress formula for wall thickness: t= vessel wall […]

What does a good prototype look like? A good prototype should look real. Clicking buttons, scrolling, anything that can make a prototype look like code. Customers react to magic with ideas. What is a successful prototype? Though some typical qualities of a successful prototype are that it: • Illustrates the real-world functionality of the product […]

What are the similarities and differences between oceanic crust and continental crust? The continental crust is made mostly of rocks with a composition similar to granite (a light-colored rock you would expect to find in the Sierra Nevada), whereas the oceanic crust is made mostly of rocks with a composition of basalt (a dark- colored […]

What are the different types of electoral system? The electoral systems currently in use in representative democracies can be divided into two basic kinds: majoritarian systems and proportional representation systems (often referred to as PR). In majoritarian electoral systems, winning candidates are those having attracted the most votes in a given electoral district. What are […]

What has an atomic number of 36? The Elements, sorted by Atomic Number Atomic Number Symbol Name 35 Br Bromine 36 Kr Krypton 37 Rb Rubidium 38 Sr Strontium Is krypton a real element? Krypton (Kr), chemical element, a rare gas of Group 18 (noble gases) of the periodic table, which forms relatively few chemical […]

What is the difference between speed and power in PE? Power is the ability to exert as much force as possible in the shortest amount of time. To put it simply, speed + strength = power. When it comes to power, you won’t be able to lift as much weight as you would if you […]

What is the importance of formulating a hypothesis? A hypothesis enables researchers not only to discover a relationship between variables, but also to predict a relationship based on theoretical guidelines and/or empirical evidence. Developing a hypothesis requires a comprehensive understanding of the research topic and an exhaustive review of previous literature. What is a broader […]

What is the net force of a rock falling at constant terminal velocity? Objects falling through a fluid eventually reach terminal velocity . At terminal velocity, the object moves at a steady speed in a constant direction because the resultant force acting on it is zero. Why does a parachutist does not fall with constant […]

Is N bigger than 2 N? n! eventually grows faster than an exponential with a constant base (2^n and e^n), but n^n grows faster than n! since the base grows as n increases. Every term after the first one in n^n is larger, so n^n will grow faster. Does N 2 grow faster than 2 […]

Why is cohesion in water important? The cohesion of water molecules helps plants take up water at their roots. Cohesion also contributes to water’s high boiling point, which helps animals regulate body temperature. How do you use the word cohesive? Cohesive in a Sentence ? To make perfect pie dough, you must mix the ingredients […]
