ANSWERPUMP Iwater pumped in 20 min = 5000 Lwater pumped in 1 min = 5000 / 20 L = 250 LPUMP IIwater pumped in 25 min = 5000 Lwater pumped in 1 min = 5000 / 25 L = 200 Llet x be the time for which pump I works and let y be the amount of time for which pump II works.then250x + 200y = 50005x + 4y = 100
An ohm per square depends on the effective area of a sheet. Let us look at a sheet that is W um by L um. A square is a calculation which answers how many squares of size min(W,L) by min(W,L) are in an area. In other words how many squares are in an area defined by W and L is max(W or L) divided by min(W or L). The number of microns would require multiplication by at least 1 dimension.
1 hr = 60 min ⇒ 1 hr 13 min = 1 x 60 + 13 min = 73 min 13 miles in 73 min → 1 mile in 73 ÷ 13 min = 58/13 min/mile ≈ 5.62 min/mile
1 day = 24 hrs, and 1 hr=60 min. Therefore 1 day=1440 min. Therefore 1 day + 4 hrs + 7 min equals 1440 min + 240 min+ 7 min or 1687 minutes. Applying the same principal to the other side of the equation gets us 360 min + 20 min or 380 min. 1687 minutes - 380 minutes = 1307 minutes. This equals 21 hrs 47 min.
Nominal diameter of deformed bars are specified by standards.Diameter of deformed bar is controlled from test :1. measure the mass w in kg weighted to a precision 0.5 %2. measure the length L in m to a precision 0.5 %The equivalent diameter is nominal diameter of deformed bars and calcolation is by this formula :Diamater = root square of ( 162.13 w / L )
