Included are my labs sheets, data I calculated, and a poor sketch of a graph at this stage. On page 52 would someone please help me to answer all the questions and the one pertaining to my graph?

I think that the problem is with the measurements and the formula used. In the formula Wi is given, while you are measuring the mass Wo of the object. Hence Wi should be written in terms of Wo.

Hence

As Wo is measured in Kg, which is the unit of mass to convert it into weight, we have to multiply it with g (acceleration due to gravity), which cancelled g from denominator.

As the volume is measured in terms of mass of the displaced water the volume of the object is given by V/w. As well as the density is required in Kg/cm3, the volume should be written as (V/)*106 cm3 = V*103 if V is in Kg and V if it is in gram. (Remember the density of water is 1 gm/cm3)

Hence the final farmula should be

In an industrial cooling process, water is circulated through a system. If the water is pumped with a speed of 0.45 m/s under a pressure of 400 torr from the first floor through a 6.0-cm diameter pipe, what will be the pressure on the next floor 4.0 m above in a pipe with a diameter of 2.0 cm?

(See attached file for full problem description)
The pipe U-band in the figure attached is connected to a flow system by flexible hoses that transmit no force. The pupse has inner diameter of 3 inches. Water is flowing through the pipe at a rate of 600 gallons/minute. The pressure at point 1 is 5 psig and at point 2 is 3 psig

The acceleration of a marble in a certain fluid is proportional to the speed of the marble squared and is given in SI units) by a=-3.00 v^2 for v greater than 0. If the marble enters this fluid with a speed of 1.20 m/s, how long will it take before the marble's speed is reduced to half of its initial value?

An open channel having a rectangular cross section is laid so that the rate of grade is 0.00048. The width of the channel is 10.00 ft, and the value of n in Kutter's formula may be taken as 0.011. When the depth of the water in the channel is 4.00 ft, the velocity computed by the Chezy formula is?

A symmetrical trapezoidal plate has the following dimensions: the widths of the parallel sides are, respectively, 2.50 ft and 4.50 ft; the perpendicular distance between those sides is 1.50 ft. the plate is submerged in a liquid in a vertical position with the parallel sides horizontal and the shorter parallel side at the top an

Hey I am about to do a lab to determine the amount of caffeine and sodium benzoate in soft drinks via HPLC. To prepare I had to answer a series of questions before the lab. I am confused on some of them and request your help. The questions are:
Why is it necessary to perform the HPLC separation at a pH of 3? How does the pH a

A sailboat is moving in the "y" direction. The wind approaches the boat at an angle of 45 degrees to the "y" direction and is turned by the sails such that it leaves in exactly the minus "y" direction.
A) If we assume that the average velocity of the incoming and outgoing wind is 10 m/s and that the mass flow rate of air being

Assume that the interior of the earth can be treated as an incompressible fluid in equilibrium. Let ? denote the density; take ? to be a constant; ? = M/V.
a.) What is the pressure within the earth p(r) as a function of distance from the center r?
b.) What is the pressure at the center, expressed in tons per square inch?
