  1. DMX is just a control protocol for intelligent lighting. Almost any new fixture can be DMX controlled in one way or another, from street lights to the sconces on a restaurant. Adding DMX would add the ability to tie the lighting in with the park-wide lighting controls. You could very easily have lighting look totally normal during the day, and then sync with the music during the fireworks.
  2. This is going to be assuming a whole lot of variables since I don't know the exact specs of the fountain, but here goes: Fountain has 112 total nozzles (source). By observation, there are (26) 1" Finger Jet Nozzles, (26) 1.5" Geyser Nozzles, (6) 2" Geyser Nozzles, and (54) 1" Geyser Nozzles. Assuming Heights of 10 feet for the Finger Jets and 1.5" Geysers, 15 feet for the 1" Geysers, and 25 feet for the 2" Geysers. Nozzle Quantity Aperture Size (in) Height (ft) Exit Velocity (ft/s) Flow Rate (each, gpm) Flow Rate (total, gpm) 1" Finger 26 1 10 25.38 62.1 1615.1 1" Geyser 54 1 15 31.08 76.1 4108.3 1.5" Geyser 26 1.5 10 25.38 139.8 3634.0 2" Geyser 6 2 25 40.12 392.9 2357.2 Total: 11714.6 To size the pumps, I assumed a head of 150ft for each run. Total guesstimate, but it would be far too complicated to do any actual calculations to determine this, especially since the pipe runs to each nozzle are going to be in the 3-4" range to get the flow rates needed for the height. HP Amps (@480/3Ø) VA Basis of Design Pump 1 GPM 1615.1 100.0 124 103092 Grundfos NBS 040-095/7.72 Pump 2 GPM 2054.152 121.0 156 129696 Grundfos NBS 050-150/14.09 Pump 3 GPM 2054.152 121.0 156 129696 Grundfos NBS 050-150/14.09 Pump 4 GPM 1816.975 100.0 124 103092 Grundfos NBS 040-095/7.72 Pump 5 GPM 1816.975 100.0 124 103092 Grundfos NBS 040-095/7.72 Pump 6 GPM 1178.622 75.0 96 79813 Grundfos NBS 030-095/7.36 Pump 7 GPM 1178.622 75.0 96 79813 Grundfos NBS 030-095/7.36 Total Power: 728293 VA 728 kVA Cost Per Hour: $35.32 So there you go- $35.32 an hour assuming a 50% demand factor on the pumps (those fountains aren't at full spray all the time). As far as water loss, on a typical summer day the evaporative losses come out to be about 2,400 gallons per hour. That is about $10/hr using the GCWW rates.
  3. That would depend on a lot of factors- outside air temp, how much the chillers are cycling, their efficiency, etc. Assuming they are using all 3 chillers at about 80% capacity (typical safety margin), that would be 7.2 MBtu/hr * 0.8 = 5.76 MBtu/hr / 0.003412 Mbtu/hr/kW = 1688.15 kW of thermal power. Using a COP of 2.8, these would consume approximately 602 kW of electrical power. At $0.097 per kWh, this would place the running cost at $58.39 per hour.
  4. By my observations, snowflake lake is using 600 tons of cooling to make the ice. That's pretty bonkers. There are three 200-ton Aggreko chillers in the fenced enclosure behind the Zamboni garage. For the other nerds out there- that's 7,200,000 BTU/hr of cooling, or 200 times larger than the typical home air conditioning system.
  5. I had it last night. Different than previous years- they are serving the macaroni without any cheese then you pick from 4 different cheeses which one you want. From memory- five alarm, brew master (beer), alfredo, and classic. I had it with Bacon jam and the brew master cheese- it was pretty tasty. Much better than CP.
  6. What I find most interesting about this is that it is designed by Joe Draves, not Alan Schilke. This will be his first RMC. Both are consultants at Ride Centerline, which has designed all of the RMCs.
  7. I have been sitting on KI drive for the last 35 minutes- crawling along. The park is about as slammed as it gets. They are parking cars in the grass next to the road. Diamondback: 150 min Orion: 180 min Banshee: 90 min Mystic: 90 min Beast: 150 min Flight of Fear: 150 min
  8. Agree with this! We did the same. The roast I had at Grain and Grill was fantastic, and so was the au gratin potatoes. I wish the sirloin at Coney BBQ was as good as that roast was (though I will still get the sirloin ) The portions at the burrito bowl place on the other side of IS were very large- more so than Hank's. I couldn't finish my bowl. Grizzly is, hands down, the worst wooden coaster I have ever been on. This year I got two more rides on it, for an all-time total of 7. It still earned that dishonor before, but this year was on a different level. The layout is really nothing too spectacular- especially the first drop that goes right into a slow turn-around. The roughness was just brutal. Rougher than Mean Streak or SOB on their worst days. If it were to get re-tracked (completely) AND get new trains, it might stand a chance at being decent. Reprofiling some of the turns and hills might give some semblance of airtime, instead of feeling like sitting on a washing machine full of rocks and getting punched by Ronda Rousey.
  9. I mean... aren't all inverts floorless?
  10. Really wouldn't be too hard- might have to beef up the footings on either side of the hole, but then you'd just run a steel beam across to catch the columns that are removed. That service road access is done just like this. Seclusion, on the other hand, is a different story.
  11. There is some construction happening in Coney Mall- pavers have been removed just outside the Kill Mart building, with what appears to be a concrete pad poured. Sheets of plywood cover the slab to protect from recent rain. Thoughts?
  12. I really liked this movie when I was there a few weeks ago. The films for the 4D theaters are produced/licensed by a company like SimEx Iwerks: https://simex-iwerks.com/shows/yogi-bear-4d-experience/ They really do have a lot of shows that they license! https://simex-iwerks.com/shows/see-all-top-4d-experiences/
  13. The building near the front of the complex is the maintenance building, which is not necessary to open the resort. My comment was regarding the delays up until this point- not necessarily why this week didn't proceed as planned.
  14. Materials have really been a challenge this year. Lumber has been well covered, but things like insulation, copper wire & pipe, even the plastic pool lounge chairs are experiencing manufacturing delays/shortages.
