Propane vs equipment

I  am curious how many fryers and grill can be operated from one 100 lb propane tank?   How many BTUs and it handle?  I have one fryer and one grill.   That is all the propane equipment I have for a total of approx 160,000 BTU.  Does anyone have similar equipment or am I expecting too much from the equipment off of the 100 lb tank.  I also have a spare 100 lb tank as backup.    Appreciate any comments.
 
Thanks

#100 lb is plenty.

1 gal propane = 4.23 lbs
1 gal propane = 91,600 BTU's, BUT the OPD valve limits = 90,000 btu/hr. All tanks 40# or less have OPD values. Some 100# tanks may have a OPD but they are not required.
 
100 lb propane tank = 23.6 gals
** At full usage it takes 24 hours to empty the 100#  tank w/ OPD @ 90,000 btu/hr or 13-1/2 hrs @ 160,000
 
If your tanks have a OPD valve you may want to look at running 2 tanks for 160, 000 BTU's worth of equipment if you run everything at the same time since the OPD valve has a 90,000 limit.

I appreciate the replies about the propane tanks and equipment.  I have a spare 100 lb tank which I will need as a spare.  Most events so far this year (which is my first yr) are only 1 and 2 days. The longest i about 8 hrs.    I have a fryer at work which is 170K and use a 100 lb tank  and it runs just fine from that.
Thanks again

I run a fryer, 4' flat top, 3' char broiler & oven from a #100lb tank.
No problems except when the temps are in the single digits or lower... then I have to turn up the regulator a bit.

i have 2, 30 pounders one i can run all my propane on at once, the other tank bothers when i run all at once i have a fryer 110,000 btu,     24 " flat top,btu's?? plus a 2 burner stove top. i found out that alot of times if i just crack the valve on the tank that bothers it is okay.. the guy at the propane place said there are different size pipes for the big plastic nuts that att. to the tanks know anything about this??

I  just ordered a 2 stage regulator in which the first stage is preset and I can adjust the second stage to allow more gas to the fryer.  Using the waer/gas ration adjustment tube I need to get around 10 to 11  but can only get around 6 on the scope.  So I hope this will do the job.
