Aventuri meter, mounted horizontally is used for measuring the flow of clean water maintained at a uniform temperature. inlet diameter =16 mm outlet diameter = 26 mm distance between inlet and outlet 89 mm pressure at inlet 115 mm of water, and pressure at outlet = 140 mm of water a)- calculate the discharge through the venturi meter, /or orifice given the pressure difference between inlet and outlet. b)-calculate the coefficient of discharge if the true flow rate is 1.6 x 104 m/sec c)-give the possible ranges of the coefficient of discharge for venturi meters and for orifice meters.

Cells in the nervous system have a potential difference of 70 mv across the cell membrane separating the interior of the cell from the extracellular fluid. this potential difference is maintained by ion pumps that move charged ions across the membrane. is this an emf? select the correct answer and explanation. 1)no. the ion pumps cannot separate charges; thus, they cannot create a potential difference. 2)yes. the ion pumps cannot separate charges, but they still can create a potential difference. 3)yes. the ion pumps can actively separate charge; thus, they can create a potential difference. 4)no. the ion pumps can separate charges, but they cannot create a potential difference.

A1.5m wire carries a 2 a current when a potential difference of 52 v is applied. what is the resistance of the wire?
