RC & RL Time Constant Calculator

The Time Constant Calculator calculates the time constant for either an RC (resistor-capacitor) circuit or an RL (resistor-inductor) circuit. The time constant represents the amount of time it takes for a capacitor (for RC circuits) or an inductor (for RL circuits) to charge or discharge 63%.

How to use a chronograph to calculate your gun's power

Q. I recently purchased an AirForceOne chronograph. I own a .22 rifle which I thought was a bit low on power. The seven shots I fired through the chronograph read 495, 499, 503, 503, 503, 507 and 503 feet per second. But converting the FPS to muzzle energy without knowing the mathematical formula has me at a loss. Can you help?.

Time Card & Timesheet Calculator

Time Card Calculator What are Time Cards? A Time Card is a card with time clock stamps used to record the start and end times of the employee's work day. Specifically, the employees enter their start time for that day, the end time, total hours worked, and overtime, if any, into the Time Card template.

PVM-21 Infrared Chronograph Oehler's reduced production of its Model 35 chronograph line has left a void in the market for high-grade chronographs. The new PVM-21 chronograph from Germany will fill that need. It has many advanced features and comes packaged with very sophisticated (though sometimes frustrating) software.

Airgun Calculator

Airgun Energy Calculator. This Airgun Energy Calculator is a simple widget designed to take the velocity of a projectile (bb, pellet, dart or bullet), its weight in grains, and calculate the foot pounds of energy (fpe) at the muzzle.

 · Free fall speed. From the definition of velocity, we can find the velocity of a falling object is:. v = v₀ + gt. where: v₀ is the initial velocity (measured in m/s or ft/s);; t stands for the fall time (measured in seconds); and; g is the free fall acceleration (expressed in m/s² or ft/s²).; Without the effect of air resistance, each object in free fall would keep accelerating by 9..

JBM

Calculates the trajectory from bullet BC and firearm info. Inputs include muzzle velocity, sight heights, chronograph distance, ballistic coefficient, drag function, line of sight and cant angles and atmospheric conditions. ... This is almost exactly like the Trajectory calculator above, but it includes inputs for ..., time ….

Standard Deviation & Load Development

Standard deviation must be considered along with everything else you know about the load. Note that the measured standard deviation includes variations in both the ammo and the chronograph. Chronograph systems with inadequate spacing between skyscreens often give passable readings of average velocity, but questionable readings of standard.

Based on the preselected distance and the detected time by the timer, the MCU will calculate and visualize the speed of the process and if you used three sensors then you can calculate the acceleration based on both speeds. This chronograph is designed by using the PIC18F/PIC18F internal timers while the internal logic is working at 48MHz.

How to use a chronograph in load development

A total of 12 shots per rifle, per range trip. (If bringing two or more rifles to chronograph loads, alternate rifles with each shot.) I shoot only four cartridges with each load to shorten the amount of time spent at the range. If you have more time you can shoot more cartridges. (Five or ….

Developing a Load for Competition Shooting, Part 1

Step 4: Load three rounds each, starting at each of the following charges: 29.2 grains, 29.6 grains, 30.0 grains, 30.4 grains. The 0.4 grain spread will produce a respectable comparison of loads. Take them to the range and test fire them across a chronograph. We know the average shooter doesn't have a chronograph, but you should.

Caldwell Ballistic Chronograph

The Ballistic Chronograph app is for use with the Caldwell line of Ballistic Chronographs supporting a 3.5mm (TRRS) line-out serial port. For best performance

Use the calculator below to calculate the kinetic energy of a bullet. In order to determine the kinetic energy, you must know the velocity of the bullet and the weight of the bullet in grains. You may add items to the list on the right in order to create a bar graph comparing the different items. This is useful for comparing handloads, muzzle.

Constant running Chrono on Speedy Pro?

 · When the chronograph is stopped, there is some friction between the steel and brass parts in this assembly. When the chronograph is started, the whole thing turns, so that internal friction is eliminated, but there is still load created by the whole assembly turning between 2 jewels.

Simply tap the screen each time to create a new wind zone then slide to the appropriate range for speed and angle. A further tap of the screen will incorporate the Coriolis Acceleration, the impact of the spin of the Earth, required for calculating extremely long shots.

Full Trajectory Calculator for Rifles, Muzzleloaders, and

To calculate the trajectory of any object you need to know four things: 1) the launch speed, 2) the object mass (weight), 3) the launch angle, and 4) the drag coefficient for the object. Using a baseball analogy, we need to know how hard we are throwing the ball, the weight of the ball, the direction of the pitch, and if we have any spit or.

How to Calculate the Distance from Lightning: 4 Steps

 · Calculate the distance from lightning in miles or kilometers. Sound travels one mile every five seconds and one kilometer every three seconds. Therefore, if you want to find out how far you are from lightning, divide the number of seconds by 5 if you want the answer in miles and divide it by 3 if you want the answer in kilometers.
