4-83 Consider a building in New York (40°N latitude) that has 76 m² of window area on its south wall. The windows are double-pane heat-absorbing type, and are equipped with light-colored vene- tian blinds with a shading coefficient of SC = 0.30. Determine the total solar heat gain of the building through the south windows at solar noon in April. What would your answer be if there were no blinds at the windows? Venetian blinds Light colored Double-pane window Heat-absorbing glass

Industry Print Exercise 23-2 Refer to print PR 23-2. The sequence of operations for this print is given below. Answer the questions following the sequence of operations. Sequence of Operations descends at a controlled rate, slowly compacting the explosive charge to avoid detonation due to a sudden Description: This is a system to control a 90-ton hydraulic, explosive-compaction press. The press ram shock. 1. The cycle is started by energizing solenoid A, which shifts control valve 3 and supplies pressure to the head end of the hydraulic cylinder (7). This operates the ram. 2. The cylinder (7) extends at a slow rate controlled by the fluid in the rod end of the cylinder, which is vented through the flow control valve (5). the 1. When de-energizes solenoid A and energizes solenoid B. This shifts control valve 3 to retract the cylinder (7). de rol valve 5 has an integral check valve that permits the free flow of fluid in the opposite direction, causing the cylinder (7) to rapidly retra…

Q-3     Three blocks A, B, and C and a grooved block D have dimensions a, b, c, and d as follows: a = 40.500  0.025 mm               b =   52.000  0.075 mm c = 73.000  0.015 mm                d = 165.900  0.250 mm  Parts A, B, and C are standard parts supplied by vendors from the market, but  we are to machine part D according to the the width that you are asked to specify.                                                (a) Determine the mean gap w0 of w and its tolerance.                               (b) Determine the mean size of d (d0) that will assure that w ≥ 0.050 mm.

Required information Sally is making a sine bar, which is used to machine angles on parts (see the given figure). She has a 1.250-inch-thick bar that needs 90° grooves machined into it for precision ground 1.0000-inch diameter cylinders. A sine bar is used by placing different thicknesses under one of the cylinders so that the proper angle is attained. Sally wants the distance between the centers of the cylinders to be D= 5.4 inches. -D -1.0000 Ø How deep should she mill the 90° grooves so that the top of the sine block is 2 inches tall? The depth of the mill should be inches.
