Episode 72- Q&A time talking trade shows, CFM, and social media posting

Standard opening episode 72   I'm excited as always to bring you chats with artist sharing stories and inspiring well helping you grow your business    Today is the first episode of our new Q and a segment where I've scan the pages of social media for questions and issues pertaining to areas of glassblowing. Today we are starting off with three that I felt stood out the most each week I will answer your questions and concerns and if you have one and would like to share it please send it to info at wiseguy radio.com I will give you full credit and a shout out with your artists name on Instagram   Before we begin please don't forget to share the show with your family and friends those that might be interested in what you do also please go to iTunes and subscribe to the show and also if you could take a minute or two and leave a review and again if you'd like to give me a message or contact me you can reach me at [email protected] and now on with the show what is the average cost of attending a trade show as a vendor?     while doing some research on this topic for myself it seemed appropriate to share this info woth you as well.. while there are several brands of trade shows the oldest and longest running is CHAMPS  which  is dedicated to the adut industrsy in general plus the tobacco and"adult novelty" show  and then AGE which is dedicted to the american made glass scene and then GlassRoots. they have several options which include room in the price.  when going to a trade show there are many factors that have to be taken into conscideration before even signing p for one which we will get into in a fiture episode  today im discussing the average cost to attend   heres a breakdown of the minimum requirements to attend   -airfare  340.00 plus  -hotel- 100.00/night  some show packages include room   -fee for show 1000.00-1500.00  -transportation while at event- depending on location you can walk or call an Uber this can average cost of 20.00 per ride (100.00) -cost of getting glass to show(ship or take with) shipping could cost around 3-500.00 depednig on size of boxes -food/entertainment 50.00/day -   approx 2,500-4000.00 depending on how extensive you want the trip to be.....   links for the events are listed below http://www.champstradeshows.com/ https://ageshowusa.com/ http://www.glassrootsartshow.com/       second question comes from a post i saw in the Torch Talk page on facebook...  new artist Angie Russell post about a ventilation exhaust setup she found on amazon that for a small shope seems to be super efficient  the question was with the fan set on high 1890 fcfm                         http://contractingbusiness.com/service/use-air-changes-calculation-determine-room-cfm       Engineering room airflow may present a real challenge when balancing an HVAC system. Most calculations only use the heat loss or gain of a room to decide on required airflow and often don’t take into consideration required room ventilation needs. Let’s take a look at how an air change calculation may simplify this step in your air balancing. What is an Air Change? An air change is how many times the air enters and exits a room from the HVAC system in one hour. Or, how many times a room would fill up with the air from the supply registers in sixty minutes.   You can then compare the number of room air changes to the Required Air Changes Table below. If it’s in the range, you can proceed to design or balance the airflow and have an additional assurance that you’re doing the right thing. If it’s way out of range, you’d better take another look. The Air Changes Formula To calculate room air changes, measure the supply airflow into a room, multiply the CFM times 60 minutes per hour. Then divide by the volume of the room in cubic feet:   In plain English, we’re changing CFM into Cubic Feet per Hour (CFH). Then we calculate the volume of the room by multiplying the room height times the width times the length. Then we simply divide the CFH by the volume of the room. Here’s an example of how a full formula works: Now, compare 7.5 air changes per hour to the required air changes for that type of room on the Air Changes per Hour Table below. If it’s a lunch or break room that requires 7-8 air changes per hour, you’re right on target. If it’s a bar that needs 15-20 air changes per hour, it’s time to reconsider.       Room CFM Formula Let’s look at this engineering formula differently. For example, what if the airflow is unknown and you need to calculate the required CFM for a room? Here is a four-step process on how to calculate the room CFM: Step One – Use the above Air Changes per Hour Table to identify the required air changes needed for the use of the room. Let’s say it’s a conference room requiring 10 air changes per hour. Step Two - Calculate the volume of the room (L’xW’xH’). Step Three - Multiply the volume of the room by the required room air changes. Step Four Divide the answer by 60 minutes per Hour to find the required room CFM:   Here’s an example of how to work the formula:       When designing or balancing a system requiring additional airflow for ventilation purposes, remember this room will normally demand constant fan operation when occupied. This may present a problem for other rooms on the same zone, so take that into consideration. Many of these rooms may require a significant amount of outdoor air. The BTU content of this air has to be included in the heat gain or heat loss of the building when determining the size of the heating and cooling equipment. Practice these calculations several times in the shop or office. Then do the calculations in the field several times over the next week to check airflow in rooms with uncommon ventilation requirements. Study the Air Changes per Hour Table to become familiar with the rooms that need more ventilation than the heating or cooling load requires.   Rob “Doc” Falke serves the industry as president of National Comfort Institute, an HVAC-based training company and membership organization.
