a) The Radiator department also wants to use the software to study fluid pressure inside the radiator of the car and, have requested you to validate the software. The rate of change of the pressure (F(t)) at any instant of time is proportional to the difference between the pressure of the liquid and a reference value as following: dF -=-(F – P/Q) dt Jse Q=65 and P=5 values. The pressure is found to be F = 1000 when t= 1 sec. where t= time in seconds.

The gage pressure of the air in the tank shown in Figure 1 is measured to be 750KP.. Determine the differential height h of the mercury column.

Suppose you have a coffee mug with a circular cross section and vertical sides (the radius is uniform, in other words). Part (a) Enter an expression for the mug's inside radius, if it holds a mass m of coffee which is of density p, when filled to a depth of h. m R= phn Part (b) What is its inside radius, in centimeters, if the mass is 375 g, the coffee has the density of water (1.00 g/cm³), and the cup is filled to a depth of 8.5 cm?

how to calculate ρ−density(lb/in3) in formula p=ρh. so for example; Find the gauge pressure (in psi) at the bottom of a freshwater swimming pool that is 12.7 ft deep.

Suppose two worlds, each having mass M and radius R, coalesce into a single world. Due to gravitational contraction, the combined world has a radius of only -R. What is the average density of the combined 4" world as a multiple of po, the average density of the original two worlds? Po Need Help? Read It

A cylinder contains a fluid at a gauge pressure of 350 kN m-2. Express this pressure in terms of a head of (a) water (Pwater = 1000 kgm-³) and (b) mercury (relative density 13.6kgm- 3).What would be the absolute pressure in the cylinder if the atmospheric pressure is at 101.3 kNm-2?

The pressure exerted on the floor by a person’s shoe heel varies in direct proportion to his or her weight, andinversely proportional to the square of the diameter of the heel. Find the particular equation when a pressure of 29.1 psiresults from a man weighing 175 pounds wears shoes with a 2.55 inch diameter heel. Using the particular equation youfind, predict the pressure (to the nearest psi) under the ¼ inch spiked heel of a woman weighing 125 pounds

Write an equation for the pressure difference ΔP between the inside and outside of the ball when it is submerged a distance y below the surface of the water.

1. Dimensional Analysis of Fluid Flow in a Pipe Consider fluid flow in a long cylindrical pipe of diameter D. A fluid with viscosity i and density p flows through the pipe with an average velocity of V. The internal surface of the pipe is rough, with the average height of the roughness being h. We wish to determine how the pressure gradient dp/dz depends on the properties of the system through dimensionless groups. (a) Identify the relevant parameters and their dimensions. (b) Determine the number of relevant non-dimensional groups. (c) Select the dimensionally-independent scaling variables. (d) Determine the dimensionless group that relates dp/dz to the other relevant dimen- sionless groups.

Consider a low-speed flight of the space shuttle as it is nearing a landing. If the air pressure and temperature at the nose of the shuttle are 121,590 Pa and 400K, respectively, what is the density? detailed solution pls, Thank you
