A horizontal cylindrical pipe discharges water (density = 1000 kg m-³) at a rate of 405 cm³.s¹. At a point where the radius is 2.41 cm, the absolute pressure is 2.57 x 105 Pa. Calculate the speed (in m-s¹) of the water flowing through the pipe at a point where the absolute pressure is 1.25 × 105 Pa.

It a lever has a mechanical advantage of 3, what does that mean? A- The work that the lever does is decreased by a factor of three. B- The lever applies three times more force than you hand can apply. C- Your hand can apply three times more force than the lever can apply.

It's saying this is not correct. Thank you for your help.

Short Answer Questions 1. Two spheres look identical and have the same mass. However, one is hollow and the other is solid. Describe an experiment to determine which is which.

Paula has worked for Brindle Corporation for 3 years.  During this time, she has worked as a machine operator/cell leader in various work cells.  Recently, the plant went to mandatory 12-hour shifts and plans to remain on this schedule for several months.   Paula’s present work cell is manufacturing 3-inch diameter exhaust tubes that are made from stainless steel.  These tubes get a hole punched in them, a flange welded on, and burrs ground off.  The pipe then gets placed into a gage to check that it was made correctly.  (The tubes weigh about six pounds.)   Paula has been performing the welding operation.  She leans into the machine and loads the part into a fixture then positions the flange.  Both pieces are clamped (using hand clamps) into position and the machine is cycled by depressing two palm buttons.   The gaging operation requires placing the finished part into the gage and clamping it (using hand clamps) into place. A pin is depressed to verify the position of the hole and a…

Help!!! Please answer all Correctly!!! Please

Need more information about number 34000 BTUhour and 20000 BTUhour ... both numbers are from where ?

The horizontal component of Force F1 (unit is in N), H1= The vertical component of Force F1 (unit is in N), V1 = The horizontal component of Force F2 (unit is in N), H2= The vertical component of Force F2 (unit is in N), V2 = The horizontal component of Force F3 (unit is in N), H3= The vertical component of Force F3 (unit is in N), V3 = The vertical component of Force F4 (unit is in N), V4 = The horizontal component of Force F5 (unit is in N), H5= The vertical component of Force F5 (unit is in N), V5 = The horizontal component of Force F6 (unit is in N), H6= The vertical component of Force F6 (unit is in N), V6 = The sum of horizontal force component for the given system (unit is in N),begin inline style sum for H of end style = The sum of vertical force component for the given system (unit is in N),begin inline style sum for V of end style = The resultant of the given force system is (unit in N), R = The direction of Resultant Force is = Short Answer question
