The tank is well insulated, so for calculation purposes the heat loss through convection and radiation is negligible.

tthe reason i'm questioning my answer is because I'm using less steam with 30# than I would be with 150# and I assumed I would have to use less 150# steam in this situation...should I be dividing by my sensible heat instead?

So I'm fairly certain that this is the way to solve the problem but my answer has me questioning the method: q = m * cp * dT q = (25,000 lbs h2o/hr) * ( 1 BTU / # * F) * (160-70 F) = 2,250,000 btu mass of steam = 2,250,000 btu / latent heat of steam pressure = mass of steam reqd.

haha yes these are pretty simple concepts, I'm a junior in college right now completing my BS in ChE. I'm interning with a company right now and I've been assigned to calculate the amount of steam necessary for a system conversion. I'm currently taking thermodynamics and do understand the...

I'm trying to determine the amount of steam required to heat a water tank on our plant. How many pounds of 30 psig steam are needed to heat 1000 gallons of water from 70F to 160F? and how do you calculate this? I think that it's: [(pounds of water) * (change in temp)] / [total heat of evap. -...

rmw: do you mean it would be easier to solve for an inlet flow or do you mean a resulting outlet flow calculating steam required? I already know the outlet flow to be 75gpm. Also, i know that this is not superheated steam so it carries a temperature of around 360F (guesstimation, not currently...

I'm trying to determine the specifications of a pickheater (direct steam injection heater) we are planning on purchasing and am new to the world of pickheaters. The pickheater is going to be used to heat incoming water from ambient (~70F) to about 150F. The steam available is a 150 psig steam...
