What else can I help you with?
What does the expression mean cream puffs on a lower shelf?
That sounds like a cooking instruction for a non-fan oven. Without a fan there are temperature zones in a [gas] oven with the lower shelves at a lower temperature than the higher shelves. In a gas cooker, the setting for gas mark is [usually] the centre shelf; the top shelf is about 1 to 11/2 gas marks higher (about 25-37oF, 14-21oC hotter), the bottom shelf is about 1 to 11/2 gas marks lower (about 25-37oF, 14-21oC cooler) - the differences will be in the cooker's manufacturer's instructions. By putting the cream puffs of a lower shelf, they are baked at a lower temperature than that at which the oven has been set, allowing the baking of something else on a higher shelf at a higher temperature at the same time.
Where you can find inclined plane on a fan?
The fan blades.
How many rotation can a fan make in 1 hour?
IF the fan speed in RPM is given, multiply this figure by 60 to find the number of rotations the fan makes in an hour.
How many non-zero angles are formed in a fan of 17 rays?
136 * * * * * Actually there are 17*16 = 272 angles. Assuming the rays do not meet at 180 degrees, each pair of rays forms two angles: one less than 180 deg and one greater.
When installing a fan shroud should the entire fan blade be inside the shroud or just half of the blade width?
At least half.
