Homework Statement The Bruce Nuclear Development is a CANDU style reactor. This means that it has a "vaccum building" to "suck" (the contents of a malfunction reactor to a safer place. Refer to the engineering "specs" for the needed information to calculate the net force of the atmposhere...

Homework Statement What would have been the force on the hatch of the Apollo 1 command module (Before the fire) during the "plugs out test" Homework Equations more info 14.8 PSI of pressure outside of the module and 17.5 PSI 1 PSI= 6 894.75729 pascals. 14.8 x 6894.74=102 042.152...

so 2721.5kg=27215 Newtons

I know the answer is 3000 pascal can somebody help me show that

Homework Statement What is the force on 1cm squared exerted by a water jet? Water jet does 6000 pounds of force per square inch Homework Equations F=P/A The Attempt at a Solution first convert 6000 pounds into kg 6000 pounds= 2 721.5kg and 1 square inch is 0.00064516 m2

Homework Statement What is the pressure exerted one the bottom of a pool in the deep end? The water is 3m deep and the dimensions are 7.5mx6m. Homework Equations volume of pool-3mx7.5mx6m=135mcubed 1m cubed= 1 ton 1000kg 135m cube= 135 tons The Attempt at a Solution 3000p

no wait F=A/P

you need to know A = F/P

the area of their foot

thanks cepheid I kinda get it now

well how many Newtons is one Earth Atmosphere pressure I know ten Newtons = 1kg arghhhhhhhhh

Homework Statement #1. What would have to be the area of a person's foot in order to impact a one Earth Atmosphere pressure? What do you need to ask? Homework Equations Earth Atmoshpere pressure= ? P=Force(Newtons)/Area(m2) The Attempt at a Solution
